Itunes 'corrupt' after upgrading to current version?

I have macbook, running snow leopard 10.6.8. This weekend I responded to the prompt to update Itunes to the newest version. After upgrading, I got the message that Itunes was corrupt (and it would not open or run). After searching for answers (including trying to update it again), I finally went through the process of deleting the corrupt Itunes.
Then I have attempted to download the latest Itunes from the Apple site; when I click 'download' I am taken immediately to the 'thank you for downloading Itunes' page, but nothing ever downloads.....
Any help/input would be most appreciated.
thanks,
Randy

Thanks but ITunes is gone (deleted corrupt version), and would not open before I deleted it. I had previously tried Yiur suggestion, then iTunes wouldn't even open after that.

Macbook locked. Cannot change security settings

I have a macbook that is password locked (we can't remember the password) and the security setup will not let me create an admin account to change users and / or settings. How can I rebuild the computer to eliminate the user and change the security settings? I can get to settings as long as I don't shut down the computer, but I can't change anything without a password. So far I have been leaving in sleep mode which does not require me to enter the password.

You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html Another resource: International Support Phone #s.
can I boot from dvd and rebuild the computer?
I don't see how, since you stated you do not have them.

Firefox would not connect after upgrade. Did system restore (XP) and not firefox wont even start

Firefox would not connect after upgrade from verion 6 to version 7. Did system restore (XP) and now firefox wont even start

Sometimes Firefox will hang during startup or shutdown, and still be running invisibly in the background. Usually in that case, you need to "kill" it either by restarting Windows or using the Windows Task Manager. It sounds as though you are familiar with opening the Processes tab, finding firefox.exe, and using End Process.
If you use an advanced firewall or other security software that tracks which programs are permitted to use the internet, please see these articles:
* [[Fix problems connecting to websites after updating Firefox]]
* [[Configure firewalls so that Firefox can access the Internet]]
A couple of other suggestions:
(1) Can you start Firefox in its Safe Mode? Hold down the Shift key when starting Firefox. You should get a two-button dialog. Click "Start in Safe Mode" (''not'' Reset). Any difference?
(2) In case your regular software missed something that is interfering with Firefox, try the scanning and clean-up tools listed in this article: [[Troubleshoot Firefox issues caused by malware]]

Firefox Mac: Flash no longer works after upgrading to latest version of Yosemite.

I'm running the latest version of Yosemite and with the recent upgrade, I can't get any video (Flash, YouTube, etc.) to run using Firefox. Works fine in Safari and Chrome. I did all of the usual permission repairs, reboots, Firefox resets, etc. Nothing seems to work. Any advice?

With a bit more digging on the net... I fixed it!
Check this crazy stuff out:

In mm.cfg is bad. Turn it off, everything's happy. Some add-in must've turned it on for me.

MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Fixed!

MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Airport says no IP is detected then suddenly reconnects?
This has been a problem I’ve been troubleshooting for the last month. I’m new to the Mac family and have loved my experience up until this point. I was under the impression that mac’s are supposed to be so user friendly that even your grandmother could use one with out having any technical knowledge. I mean I shouldn’t have to be deleting drivers or reformat my mac because of an OS update glitch? (That’s what the guy at the Genius Bar told me to do.) What I refused to succumb to was that I’m really good with computers. I get at least a phone call every other week from someone asking me for tech support. So I’d like to think that nothing I’ve done to the system would have caused this anomaly.
After numerous attempts of troubleshooting and researching forms I believe I’ve discovered a solutions that seems to be working for me.
Here are the steps I took to create a consistent connection to my Wi-Fi. I believe it was a combination of all these steps to create success.
1.) Changed my router to use G Wireless Only. (I’m assuming this removed any unnecessary frequencies to allow G to broadcast stronger?)
2.) Did a scan on the other networks in my area to find out what channel everyone else was broadcasting on. Copy and past the text below into a terminal window.
sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resourc es/airport /usr/sbin/airport
This will allow you to simply type “airport” in the terminal window to execute the command.
Type airport –s
This will display all the networks in your area and what channel they are broadcasting on.
3.) Changed my router to use a channel that no one in my area was using. (This helped to make my network stronger and free of interference.)
The last steps will help your home network improve but these next steps I believe helped fix any install errors caused maybe by the 10.6.5 update on my mac.
4.) Boot your Mac into safe mode by holding down the shift key while booting.
5.) Open System Preferences and Click on Network.
6.) Click the drop down menu from Locations at the top of the screen. Click edit locations..
7.) Create a new location by clicking the + and give it a new name.
8.) Delete the old location by clicking on the old locations name and click the – to remove.
9.) Reboot
10.) Open System Preference and click on Network.
11.) Click on the settings sprocket next to the + and – and click on Set Service Order…
12.) Drag Airport to the top of the list of devices then click Ok.
Now this last step is what seemed to eliminate the issue. I hardcoded my IP address to my network. This way my computer will always use the same IP and not have to search.
13.) Click on Advanced under Network.
14.) Click on TCP/IP. Click on the drop down for Configure IPv4 and change it to Manually.
15.) Fill out the fields with your IPv4 Address: 192.168.1.1xx (x=whatever number) Subnet Mask: 255.255.255.0 Router: 192.168.1.1 (All of these settings are pretty standard for most home networks.)
16.) Click on the drop down for Configure IPv6 and change it to Off.
17.) Next click on the DNS tab at the top.
18.) Click the + to add a DNS Record.
To find your DNS Server open a Terminal window by launching Applications --> Utilities --> Terminal
Then Type cat /etc/resolv.conf
(There is a space between cat and /. Without it you’ll get no such file or directory.)
This should return two addresses. Your ISP’s DNS Servers.
19.) Add both records to the DNS and click Ok.
20.) Click Ok then under Network Click Ok.
21.) Reboot router then Mac
22.) Fixed my connection issue
The symptoms I experienced eluded me to believe that something with the DHCP is going into an idle then disconnecting. Before when DHCP was set to automatically assign the network signal would time out then searchers for a new IP resulting in Airport displaying No IP is detected. By setting my IP to a fixed address I still notice a slight drop in bandwidth at moments but because of the assigned IP I never loose connection. I can now stream video, play games, chat all without getting disconnected.
I believe this fix will work for my home network but I also noticed this issue at work so for each location that I connect for the time being I’ll create each there own location and hardcode the IP address to that network. I’ve been reading that 10.6.6 is coming soon so maybe this will be resolved for good in the next update.
Let me know if this helps or if you have any questions.
Best of luck.

I have been having the same issue for the last two weeks. No real indication as to why it ever began other than I had turned off my router and Airport Extreme Base Station off for a weekend while I was away from my place.
iPad, iPhone, iPod Touch, all have no issues at all with my Airport Extreme Base Station. Can stay connected throughout my living room, bathroom, bedroom, no issues whatsoever.
My 5 month old MacBook Pro 2.66 GHz Core i7 Airport is sometimes perfect, able to connect, DHCP, and browse without issue. Then, for no reason, I won't be able to join my wireless network, or when I can join, I can't pick up an IP address. And then it will connect, pick up and IP, and then it won't browse. No real rhyme or reason to when this will happen, or when it works.
I thought that it was an issue with my MacBook Pro, but then my sister visited with her brand new MacBook Pro 2.26 Intel Core 2 Duo, and while a month ago she was able to connect, DHCP, and browse without issue, this weekend she had all of the same issues I was having.
My XBOX 360 and MacBook Pro have absolutely no issues with the wired connection. Only my WAN seems to have this issue.
Did you ever find anything more to this?

ISCSI initiator not connecting after upgradation

HI,
iSCSI initiator not connecting after upgradation from windows 2003 STD to windows 2008 STD R2 server, upgradation was successfully completed, except Microsoft iSCSI initiator connectivity, the initiaor interface show it as 'reconnecting'....!!!!!
Kindly guide on this.
Thanks in Advance

HI Shaon Shan,
Thanks for the info.
While searching for the file names start with iscsi in c:\windows\system32 folder the file version is 5.2.3790.3825 in working windows 2003 server.
Recently I've downloaded (Not yet installed) iSCSI initiator for Windows 2008 from Microsoft website in that iSCSI initiator file version shown as 6.3.4.1, instead of using inbuilt Microsoft iSCSI initiator in W2K8, shall I try installing the downloaded
version,
because when I checked in Windows 2008 (Upgraded version) the iSCSI file version remains the same as 5.2.3790.3825 which was found in windows 2003.
Post to our previous discussion
While I'm trying to install the new iSCSI initiator for Windows 2008 downloaded from Microsoft website, it shows some error "Setupcould not find the update.inf file needed to update your system" then I've updated my server, but no luck still showing the
same....!!!!

I attempted to uninstall QT and reinstall- the QT 7.4 installer failed to install (it said a more up to date version was present, even though I'd trashed the old one). I downloaded and reinstalled 7.5 but itunes still did not work.
While my solution wasn't ideal
1) It was what Apple told me to do!
2) It seemed preferable to A) A complete system reinstall, B) removing 264 .plist files one at a time, rebooting, and seeing which one was causing the problem.
I still have the old .plist files in another folder, and can replace them in my preferences folder if I decide I need them. Most apps will create a new .plist file on start-up if there is not one present, so unless it is a program where I have gone to great lengths to change preferences from default, I'm guessing I will not notice much difference (and if I do, I can always go to my archive of .plists, or on Time Machine for that matter...)

Try to decrease the value of the pref <b>network.http.max-connections</b> from 256 to 30 as used in Firefox 3 versions.

The application uninstaller ,created with Labwindows CVI, doesn´t work after upgrading to 2010 version

Hi,
I have been working with Labwindows CVI 2009 with no problem but after upgrading to 2010 version I have the following problem:
When i´m going to execute the unistaller, either from Windows Control Panel or directly from the uninst.exe icon, it doesn´t work. The PC thinks a few seconds and does nothing, and it happens with all the applications I build with Labwindows CVi 2010.
Thanks,

Hello -
Are you installing these distributions on a non-English operating system? If so, the first thing to try would be the workaround listed on this known issue.
The known issue only lists Italian OSs as the troublesome OS, but it could actually happen on many different non-English OSs. I will update the text accordingly the next time I update the known issues list.

Please help me. My YouTube app will not work. Every time I open it says 'cannot connect to youtube'. I have searched for help and tried resetting my settings and rebooting my ipad2 but nothing has solved the issue.

Yes, I am connected to the Internet through my wifi. Everything is working fine with the e eption of youtube. I have reset all Internet settings and have tried synching to iTunes followed by rebooting. This is all the advice I have found although none of it has been helpful.
Has anyone else encountered this problem?

I just upgraded my iPad to ios6. Now my Epson iPrint crashes all the time. I called Epson and they had no answer...said to use AirPrint instead. But AirPrint stinks because you cannot change printer settings. Anybody know how to make iPrint work on ios6?

Anybody know how to make Epson iPrint work on ios6? Epson told me to use AirPrint, which stinks because you cannot change printer settings.

Epson needs an update to their app to support ios6. I'm sure they will in time.
Try deleting it and re download it. If that doesn't work, it's what I said above. :(

can anyone help?Search the bugs database to see if someone else already reported this; if not create a new bug entry. Whatever mistake you could make, you should not be getting a NullPointerException as a result so this is at the very least a bug in the error handling of webstart.
But just some observations to try and see if you can make a difference (which is added input for your bug report). If I check JNLP examples, I see that the url specified is usually without a protocol, so it could be like this:
<jar href="/resources/applet/formeditor.jar" />The JNLP should be on the host that you service the jar from, so Webstart can fill in the host information for itself.
Also you provide a main-class; if the jar manifest specifies a main-class (and it should) you don't need to specify it in your JNLP file.
