Welcome to the Apple Support Communities
The music is stored on the iTunes library. This library isn't deleted when you uninstall or reinstall iTunes, so you will keep everything. Anyway, it's better to make a backup of the library. Apart from that, you can download the purchased music as many times as you want

Need to install AdobePDF.dll in Acrobat 8.0 then download update 8.1, couldn't do it during install as hatch wouldn't open because Adobe Acrobat disc was in it for the install.

During the reinstall of Acrobat 8.0 on my Vista 64 bit computer (on a new harddrive) I was asked to insert the Win Vista Install Disk but was unable to do it. Evidently I need to get the 'AdobePDF.dll' file installed and don't know how to do that. When I tried to check for updates, I got the error message: "There are no updates at this time. ...updates can';t be determined at this time." How do I get the needed file installed.

Here's a screen copy of the message:

Okay. Not an issue with a damaged AVFoundationCF.dll file either then, because the Apple Application Support has been swapped out.

How to install how to install CWAnalysisControlsLib.dll when installing MS 2013 for VB 2010

I am trying to reuse software and need to install CWAnalysisControlsLib.dll when installing Measurement Studio 2013 for VB 2010.

Tomrace,
A lot of our ComponentWorks DLLs are no longer installed with MeasurementStudio 2013; you'll need to install an older version of MS and then get the DLL from that installation. What version of MS were you using prior to MS2013?
I was able to find cwanalysis.ocx in the MS 8.1.2 install; is the ActiveX server what you're looking for?

Installed vi dll on a target PC doesn't return results

I have developed a VI that reads data from a NI-9215A, filters it, FFTs it, and picks out a single peak. The vi returns two doubles, for frequency and amplitude. Using Application Builder I created a DLL that I call from the C++ application. All of this works fine on the Labview development PC. Next, I need to install the DLL on a different PC where my Visual Studio development environment exists. So I created an installer to install the DLL on a different PC that doesn't have Labview installed. In the installer I included the LabView Runtime Environment and the DAQmx driver.
On the target PC, my C++ app seems to access the DLL (pauses the expected length of time to get data back), but then invalid data is always returned -- "0" for the frequency and "-1.$" for the amplitude. I can remove the DLL and the application throws an exception because it can't find the DLL, so I know it is accessing the DLL. I just can't get it to return correct data.
I have copied the following files from my DLL installation folder on my Labview PC to the executable folder for my C++ application on my Visual Studio PC:
DllFileName.aleases
DllFileName.dll
DllFileName.h
DllFileName.ini
DllFileName.lib
data\lvanlys.dll
Any idea what I might be missing or why I can't get it to return valid data? I do have a valid signal going into the 9215A.

Hi SilverTop,
How do you have the NI-9215 connected to the second computer? Are you using a cDAQ chassis or USB? If you are using USB, you will also need to include the NI-VISA driver in your installer.

Update to 10.7 did not work, cannot access iTunes. Need AVFoundationCF.dll, Ituneshelper not installed correctly, Error 7 (Windows Error 126), Error 7 (Windows Error 5)

I am running Windows 7 64 bit.
This HORROR began because I realized that my phone had suddenly lost all of the music except music that had been purchased. It also lost all purchased iBooks as well as audible books downloaded from audible and ringtones that I had purchased from iTunes.
I then thought that it would be fine once I connected to itunes on my computer. I connected to itunes and it said that there was an update available so I downloaded and installed 10.7.
I tried to run the program and got Error 7 (Windows error 5) message.
I then found several discussion questions that seemed similar to mine and I think that I tried them all. Removed everything apple and reinstalled iTunes. I followed the instructions and removed everything in the order that was listed, some I had to change security to own the file before I could delete them. I did all of the steps, (maybe I deleted too many apples items ??) emptied the recycling bin, restarted and reinstalled. I also tried the Net framework fix, used the ms fixit (the one with the picture of the man on it) and I think a few other things that I have found on this site as well as MS site. I restarted my computer every time.
The latest thing that I tried was to download 10.63 since I don't care about the new stuff. After all of this I sometimes get and message saying that I am missing AVFoundationCF.dll file and once it said something about Itunes Helper (when these two messages appear, it is separate from the error messages which occur after clicking ok on them) before getting the Error 7 (windows error 5) or else Error 7 (Windows error 126).
PLEASE HELP!

Follow the instructions on this link, basically un-install everything, remove programs that says they are made by apple inc. (using add remove program)

You will also need to check and verify that the following folders have been removed:
C:\Program Files\Bonjour
C:\Program Files\Common Files\Apple
C:\Program Files\iTunes
C:\Program Files\iPod
C:\Program Files\QuickTime
C:\Windows\System32\QuickTime
C:\Windows\System32\QuickTimeVR
dont forget to remove icloud also
you dont need to delete your itune music library though
If any of these folders still exist, delete them along with their contents. (if you cant delete them, right click and go to properties and then security and change the control of the fold to you)
do this for files under program files and program file (x86) on your computer
once you have deleted everything, restart your computer. Then I repaired my registry using a registry repair program.
Important:- instead of installing itunes I installed quick time, which installs apple application support (this is the corrupt file which is causing all the issues)
i then installed itunes and it all worked fine,
should take no longer than half hour to fix
hope this helps

While running an update in Itunes i received an error message - Unable to locate component because AVFoundationCF.dll was not found. Then Itunes was not installed correctly. Error 7 (windows error 126) Do I have to reinstall and will I loose all my music?

While running an update in itunes (not installing), it stopped in the middle of the update and i receceived the following messages:
Application failed to start because AVFoundationCF.dll was not found. Reinstalling itunes may fix the problem. Then "itunes was installed incorrectly. Please reinstall itunes Error 7 (Windows error 126)". If i uninstall and reinstall itunes will I lose all of my music, etc.?

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall press on)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

When opening iTunes I continue to get the same messages, 'The program can't start because AVFoundationCF.dll is missing' and 'iTunes was not installed correctly. Error 7 (Windows error 126)' I've uninstalled, reinstalled many times - nothing! help please.

When opening iTunes on my new Windows 7 PC I continue to get the same messages, 'The program can't start because AVFoundationCF.dll is missing' and 'iTunes was not installed correctly. Error 7 (Windows error 126)' I've uninstalled and reinstalled many times to no avail, even tried it on a different user account and still nothing. I recently installed Panda Internet Security 2012 (about 12 days ago), initially iTunes worked fine as usual but within the last few days I've been unable to open it with the same messages appearing. I've read through some of these pages and tried everything that's been advised, uninstalling and reinstalling while internet and laptop security is swithched off, downloading tools to completely remove anything related to iTunes, tried it in Safe Mode, nothing has worked. I've also noticed that in the start menu when I click on iTunes, it says '(empty)' where it should have the logo and ability to start the program, does this mean it doesn't download + install properly each time I've tried? Any help would be enormously appreciated.

Doublechecking. Have you also tried the following user tip?

all of a sudden my itunes wont come up when i hit the desktop icon. un and re installed many times, tried new users, it finally gave me "you need to reinstall sqmapi.dll " im a noob and i have know idea what that is or where i can get it. i cant open any file or library that has anything to do with itunes except safari and quicktime are fine. im about to pull out whats left of my hair.

Okay, that's got one thing ruled out at least.
Can you check something for me, big? I'd like to see if iTunes launches with the Bonjour Service disabled.
In your Start menu, right-click Computer and select "Manage".
Expand "Services & Applications".
Open "Services". (Perhaps maximise the screen to better see what's going on.)
Right-click the Bonjour Service and select "Properties".
In the General tab, set the Startup type to "Disabled":
... and click OK.
Restart the PC and try launching iTunes. Does it open this time?

After installing update itune 10.5 will not open or run on windows 7 pc keeps telling me error 7 126 and that AVFoundationCF.dll failed to load. reinstall.I have done the complete 6part unistall 10 times now and each time I get the same thing anyone have

So I installed the latest update of Itune on my Windows 7 Ultimate 64 bit PC.( the previous versions worked fine never a problem)
It installs, and comes up with error7 126. Reinstall program again.
So I go through all six steps to unistall, and reinstall a frsh downloaded compy of 64 bit Itune from Apple Site. and reinstall again and again, went through this process 10 times still having same problem, including now also comes up with AVFoundationCF.dll missing, try to install that won't install.
So now I can not use anything apple, iteunes, safari, update etc, nothing will work, which means I can no lobger sync or update my Iphone 4S.
Does anyone have an answer for me????

I'm an applications developer and also run a part-time videography business. As such, I require more than 3.12GB of RAM. That is the physical limitation of a 32bit system. Pointless to stay on 32bit if you plan on having more than that much RAM.
I'm also not about to pay someone to fix my PC when I can do it myself. I was originally hoping for someone who had experienced the problem before to point me in the right direction so I didn't have to spend so much time trying to figure out what the issue was for myself.
Basically, in the end the problem was caused because right at the point in time when I chose to uninstall, and reinstall; Apple released a new version of iTunes. This version in turn had a requirement of iOS 4.2 to sync with the iPhone. This is a pretty embarrassing for Apple that they would release software reliant on other software before said software was released.
Had I realised I was downloading a newer version at the initial point of installation, this wouldn't have been an issue. I could've easily have rolled back iTunes to the previous version and gotten on with my life.
Another issue is that iTunes is not actually a 64 bit application. It masquerades as one to allow installation on the 64 bit platform.

In the normal course of events, an uninstall/reinstall doesn't touch your content files. (That being said, it's always a good idea to have a backup in case of disasters.)
