Bnoir i need your help! Folder path itunes.resources invalid character
Hey all,
I am trying to update a previous install of itunes, and get an error (with no error number) that says: "The folder path Itunes.resources contains an invalid character" followed by another popup error: "Problem with shortcut: fatal error during installation". I get the same error when trying to remove itunes in the control panel add/remove utility. Any ideas on how to fix this problem?
thanks in advance.
"Invalid character" messages usually seem to indicate that some of your registry entries are pointing to a different disk location than the files/folders referenced in the message are actually on.
I've got a link to specific instructions for these messages when they reference the "My Pictures" directory. However, rather than initially trying to adapt those to the itunes.resources case, let's see if we can instead get past this using the Windows Installer CleanUp utility.
let's try the following procedure.
First, head into your Add/Remove programs and uninstall your QuickTime. If it goes, good. If it doesn't, we'll just attend to it when we attend to iTunes.
Next, download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
Now launch Windows Installer CleanUp ("Start > All Programs > Windows Install Clean Up"), find any iTunes and/or QuickTime entries in the list of programs in CleanUp, select those entries, and click “remove”.
Next, we'll manually remove any leftover iTunes or QuickTime program files:
(1) Open Local Disk (C:) in Computer or whichever disk programs are installed on.
(2) Open the Program Files folder.
(3) Right-click the iTunes folder and select Delete and choose Yes when asked to confirm the deletion.
(4) Right-click the QuickTime folder and select Delete and choose Yes when asked to confirm the deletion. (Note: This folder may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(5) Delete the QuickTime and QuicktimeVR files located in the C:\Windows\system32\ folder. Click Continue if Windows needs confirmation or permission to continue. (Note: These files may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(6) Right-click on the Recycle Bin and on the shortcut menu, click Empty Recycle Bin.
(7) Restart your computer.
Now try another iTunes install. Does it go through properly now?

\Folder path contains an invalid character. \
I bought and Ipad plugged it into my computer and itunes said i needed the newest version of itunes to run the ipad. So i tried downloading version 10.6.1 and it said errors occurred while installing updates.If problem persists choose tools>download only and install manually. So i did that and then it said folder path contains invalid character. and it wont let me install it. I contacted itunes support and they told me to uninstall itunes which i tried doing but once again the same message poped up folder path contains invalid character. Cant get apps i had before on ipad without syncing to itunes please help.

IPOD Updater - Error 1324 - The Folder path contains an invalid character
I tried to install ITUNES on an external HD (I didn't want to slow down my computer by putting all of my music on my internal HD). ITunes installed and then crashed. I removed all traces of ITUNES and IPOD that I could find and went to install ITUNES again on my regular internal drive. Now it goes through the installation and REMEMBERS my IPOD serial number (so obviously I can't find all of the files to remove) but doesn't give me a choice of where to install (it still must be trying to install to my external HD) the ITUNES. All I get is the following Error message:
IPOD Updater - Error 1324 - The Folder path "Program Files" contains an invalid character
Does anyone have a solution out there?
Thanks in advance!

Interesting. It's choking on the old iPod updater application. (iPod software updates are no longer handled by a standalone application ... that function was folded into iTunes beginning with iTunes 7.0.0.70.)
Let's try the following procedure.
Download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
Now launch Windows Installer CleanUp ("Start > All Programs > Windows Install Clean Up"), find any entries called "ipod for windows \[date]" or "ipod updater \[date]" or just "ipod for windows" in the list of programs in CleanUp, select those entries, and click “remove”.
Quit out of CleanUp, and restart the PC.

I want to get iBook, Facebook and Skype to my iphone 4.2.1 through my iTune, but I coudn't because it is said that it requires a newer version of iOS. Please I need your help. Thanks
If your iPhone can't be updated to a higher iOS version then the only way to get them is if you downloaded versions of them which were compatible with iOS 4.2.1 and you still have copies of those versions somewhere e.g. on your computer or on a backup - only the current version of each app is available in the store, and as apps (and other content) are tied to the account that downloads them, you will need to have older copies that are linked to your id

Hi, my iphone its in recovery mode and when i restore my iphone 5s loading show the blue screen and show note on itunes (unknown error 14) please i need your help please . thanks
In the article Resolve iOS update and restore errors this is what it says about error 14:
Check your USB connections
Related errors: 13, 14, 1600, 1601, 1602, 1603, 1604, 1611, 1643-1650, 2000, 2001, 2002, 2005, 2006, 2009, 4005, 4013, 4014, or “invalid response."
If the USB connection between your device and computer is interrupted, you may be unable to update or restore.
To narrow down the issue, you can also change up your hardware:
Use the USB cable that came with your device, or a different Apple USB cable.
Plug your cable into a different USB port directly on your computer. Don't plug it into your keyboard.
Try a different computer.
If necessary, resolve any further issues with the USB connection, then with your security software.
If you're still seeing the error message, check for hardware issues by following the next section. -
I tried to update to IPad 5.1, but when it finished and tried to restore the backup, it shows me that Itunes could not back up because a session could not be started with iPad. need your help please
This has happened to me a couple of times and what I do is quit iTunes and restart my Mac and then try again and then it will work.
If iTunes has already created the backup, you should still be able to restore from the backup when you are connected to iTunes. Right click on the iPad name on the left side of iTunes and select restore from backup. After the process completes, sync with iTunes to transfer all of your apps, music, photos and other media back onto the iPad. -
I need your help with a decision to use iPhoto. I have been a PC user since the mid 1980’s and more recently have used ACDSee to manage my photo images and Photoshop to edit them. I have used ProShow Gold to create slideshows. I am comfortable with my own folder and file naming conventions. I currently have over 23,000 images of which around 60% are scans going back 75 years. Since I keep a copy of the originals, the storage requirements for over 46,000 images is huge. 180GB plus.
I now have a Macbook Pro and will add an iMac when the new models arrive. For my photos, I want to stay with Photoshop which also gives me the Bridge. The only obvious reason to use iPhoto is to take advantage of Faces and the link to iMovie to make slideshows. What am I missing and is using iPhoto worth the effort?
If I choose to use iPhoto, I am not certain whether I need to load the originals and the edited versions. I suspect that just the latter is sufficient. If I set PhotoShop as my external editor, I presume that iPhoto will keep track of all changes moving forward. However, over 23,000 images in iPhoto makes me twitchy and they are appear hidden within iPhoto. In the past, I have experienced syncing problems with, and database errors in, large databases. If I break up the images into a number of projects, I loose the value of Faces reaching back over time.
Some guidance and insight would be appreciated. I have a number of Faces questions which I will save for later.Bridge and Photoshop is a common file-based management system. (Not sure why you'd have used ACDSEE as well as Bridge.) In any event, it's on the way out. You won't be using it in 5 years time.
Up to this the lack of processing power on your computer left no choice but to organise this way. But file based organisation is as sensible as organising a Shoe Warehouse based on the colour of the boxes. It's also ultimately data-destructive.
Modern systems are Database driven. Files are managed, Images imported, virtual versions, lossless processing and unlimited editing are the way forward.
For a Photographer Photoshop is overkill. It's an enormously powerful app, a staple of the Graphic Designers' trade. A Photographer uses maybe 15% to 20% of its capability.
Apps like iPhoto, Lightroom, Aperture are the way forward - for photographers. There's the 20% of Photoshop that shooters actually use, coupled with management and lossless processing. Pop over to the Aperture or Lightroom forums (on the Adobe site) and one comment shows up over and over again... "Since I started using Aperture/ Lightroom I hardly ever use Photoshop any more..." and if there is a job that these apps can do, then the (much) cheaper Elements will do it.
The change is not easy though, especially if you have a long-standing and well thought out filing system of your own. The first thing I would strongly advise is that you experiment before making any decisions. So I would create a Library, import 300 or 400 shots and play. You might as well do this in iPhoto to begin with - though if you’re a serious hobbyist or a Pro then you'll find yourself looking further afield pretty soon. iPhoto is good for the family snapper, taking shots at birthdays and sharing them with friends and family.
Next: If you're going to successfully use these apps you need to make a leap: Your files are not your Photos.
The illustration I use is as follows: In my iTunes Library I have a file called 'Let_it_Be_The_Beatles.mp3'. So what is that, exactly? It's not the song. The Beatles never wrote an mp3. They wrote a tune and lyrics. They recorded it and a copy of that recording is stored in the mp3 file. So the file is just a container for the recording. That container is designed in a specific way attuned to the characteristics and requirements of the data. Hence, mp3.
Similarly, that Jpeg is not your photo, it's a container designed to hold that kind of data. iPhoto is all about the data and not about the container. So, regardless of where you choose to store the file, iPhoto will manage the photo, edit the photo, add metadata to the Photo but never touch the file. If you choose to export - unless you specifically choose to export the original - iPhoto will export the Photo into a new container - a new file containing the photo.
When you process an image in iPhoto the file is never touched, instead your decisions are recorded in the database. When you view the image then the Master is presented with these decisions applied to it. That's why it's lossless. You can also have multiple versions and waste no disk space because they are all just listings in the database.
These apps replace the Finder (File Browser) for managing your Photos. They become the Go-To app for anything to do with your photos. They replace Bridge too as they become a front-end for Photoshop.
So, want to use a photo for something - Export it. Choose the format, size and quality you want and there it is. If you're emailing, uploading to websites then these apps have a "good enough for most things" version called the Preview - this will be missing some metadata.
So it's a big change from a file-based to Photo-based management, from editing files to processing Photos and it's worth thinking it through before you decide. -

I've tried to execute J2ee tutorial examples.
I don't know why this sample didn't execute...I've already finished to set up J2EE and enviornment variables.
I was trying this part from j2ee tutorial titled as "Packing Web modules".
Whenever I type "asant create-war" to make web modules in command window. I always got error.
Packaging Web Modules(From J2ee tutorial for your information)
A web module must be packaged into a WAR in certain deployment scenarios and whenever you want to distribute the web module. You package a web module into a WAR using the Application Server deploytool utility, by executing the jar command in a directory laid out in the format of a web module, or by using the asant utility. This tutorial allows you to use use either the first or the third approach. To build the hello1 application, follow these steps:
In a terminal window, go to <INSTALL>/j2eetutorial14/examples/web/hello1/.
Run asant build. This target will spawn any necessary compilations and will copy files to the <INSTALL>/j2eetutorial14/examples/web/hello1/build/ directory.
To package the application into a WAR named hello1.war using asant, use the following command:
asant create-war
This command uses web.xml and sun-web.xml files in the <INSTALL>/j2eetutorial14/examples/web/hello1 directory.
To learn how to configure this web application, package the application using deploytool by following these steps:
Start deploytool.
Create a web application called hello1 by running the New Web Component wizard. Select FileNewWeb Component.
In the New Web Component wizard:
Select the Create New Stand-Alone WAR Module radio button.
In the WAR File field, enter <INSTALL>/j2eetutorial14/examples/web/hello1/hello1.war. The WAR Display Name field will show hello1.
In the Context Root field, enter /hello1.
Click Edit Contents to add the content files.
In the Edit Contents dialog box, navigate to <INSTALL>/j2eetutorial14/examples/web/hello1/build/. Select duke.waving.gif, index.jsp, and response.jsp and click Add. Click OK.
Click Next.
Select the No Component radio button and click Next.
Click Finish.
Select FileSave.
A sample hello1.war is provided in <INSTALL>/j2eetutorial14/examples/web/provided-wars/. To open this WAR with deploytool, follow these steps:
Select FileOpen.
Navigate to the provided-wars directory.
Select the WAR.
Click Open Module.
I guess this step is for checking my system about setup information. I not sure how to change it.

Thank you in advance.ok,
First of all make sure your tutorial folder is installed from the root:
C:\javaeetutorial5
or
D:\javaeetutorial5
it makes things so simple.
Secondly:
set your jee tutorial home
JAVAEE.TUTORIAL.HOME =
C:/javaeetutorial5
Thirdly: check in:
C:\javaeetutorial5\examples\bp-project
make a copy of the build.properties.sample save it as build.propropties, as a property file,
edit the properties file as in:
build.properties
As follows:
# uncomment the property javaee.home, and add the path
# to your GlassFish Java EE 5 SDK installation
javaee.home=c:/Sun/SDK
javaee.tutorial.home=c:/javaeetutorial5
# Uncomment the property j2ee.server.username,
# and replace the administrator username of the app-server
javaee.server.username=admin
# Uncomment the property j2ee.server.passwordfile,
# and replace the following line to point to a file that
# contains the admin password for your app-server.
# The file should contain the password in the following line:
AS_ADMIN_PASSWORD=admin1234and so fourth. Some of the settings as the application server name is all done for you
and then test it again.
Take care of editing the property file. It can give you headache.
Note also that this is for application server 9.1 - JEE5.

Need your help on performance issue please
Hello everyone!
I need your help to understand an effect I notice with a Thread class I built. I currently work on enhancement of my application Playlist Editor (see http://www.lightdev.com/page74.htm) and a new release will be available soon.
Among other extensions the new release will have a title filter function which is based on audio data that is recursively read from ID3 tags of files found in a given root directory. The data collection is done by a CollectionThread class which reads into a data model class AudioDataModel and the entire process works fine, no problem with that.
However, when my application is started for the first time the CollectionThread runs approximately 3 minutes to collect data from approximately 4300 audio files on an Intel Pentium M 1,4 GHz, 512 MB RAM, Windows XP SP2. When the application is shut down and started again, it takes only a few seconds to do the same task for all subsequent launches.
I already tried to start the application with java option -Xms40m to increase initial heap size. This increases performance in general but the effect is still the same, i.e. first run lasts significantly longer than subsequent runs.
I also tried to build a pool mechanism which creates many empty objects in the data model and then releases them to contain the actual data at is being read in but this did not lead to better performance.
It must have to do with how Java (or Windows?) allocates and caches memory. I wonder whether there is a way to pre-allocate memory or if there are any other ideas to improve performance so that the process always only takes seconds instead of minutes?
I attach the key classes to this message. Any help or ideas is much appreciated!
Thanks a lot a best regards
Ulrich

All classes posted here do not need debugging, they already have proven to run error free. The classes are only posted for information for the interested reader - no need to go through all the stuff in detail - only if it interests you.
My application calls class CollectionThread wich is a subclass of InfoThread. CollectionThread recursively goes through a directory and file structure and stores found ID3 tag information in instances of class ID3v11Tag which in turn gets stored in one instance of class AudioDataModel. All classes are shown below.

*Hi Franck,
thank you, mate. I did what you suggested (changed class attached) but that did not change the mentioned behaviour.
The first run is approximately 75 seconds with Java option -Xms40m and approx. double without, the second run and all subsequent runs are only 2-3 seconds each (!!!) even when terminating and re-starting the application between thread runs.
I'm pretty clueless about that, any more help on this anyone?
Thanks a lot and best regards
Ulrich

I'm lost when I try to figure out what exaclty is Java.... I need your help
Hi, I know that java is OOP, Multiplatform, etc, etc...
But when I try to look on google for jobs about java or "learn Java" what "Should I know in java"... I always found... whebshpere, oracle, linux, jboss, glassfish, opensolaris, struts, hibernate, spring, eclipse, netbeans, jidea, and so on!!!...
I'm lost... I will be sincere ...
I've started thank for a friend in a world of programming with .NET (ASP.NET SQL .NET Silverlight Windows Server) and was good BUT i feel inside that I prefer Java.
I don't know why but with java I feel free, i think will be a good technology for a long time.
But some things make my crazy.
I cant found a fast path or the right path without getting mess. Like I posted above.
So I need your help, if You are an advance programmer... tell what Should I learn ( essencially ) to get a good job. Oracle + Java ? linux + oracle + java? websphere + java? eclipse or netbeans?? all thouse things are awesome... but I am a HUMAN... I can't learn thouse all things and less in little time.... I just want to have a good preparation for to start to look a job in early time.
I look forward yours answers.

I know great developers that never have written a single SQL statement, and I'm always trying to stay away from everything that has a web interface :)
Decide what you want to do at work, and then figure out what technologies you need to know. -

Which system are you getting the error, XP / Win 7 ?
Please find the minimum H/W requirement (Source Inst Guide)
Minimum RAM :- 4GB
Paging file size :- 1 times RAM plus 8 GB
If you are trying for win 7, then I would recommend you to
increase the swap space and give it a try.
It looks like it is not getting the required system

Stop being impatient.
From the article that the question was posted from:
Errors related to downgrading iOS
The required resource cannot be found: This alert message occurs when your device has a newer version of iOS than what is available in iTunes. When troubleshooting a device that presents this alert message, go to Settings > General > About and check the version of iOS on the device. If it is newer than the latest released iOS version, the device may have a prerelease developer version of iOS installed. Installing an older version of iOS over a newer version is not supported.
Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.
You cannot downgrade.
If you have a 3GS, you can only install iOS 6.1.3 which is the current version of iOS for the device.
