Launching itunes error miniplayer.dll

When I launch itunes on my laptop I receive an error that says "error writing to file C:\program files\itunes\itunesminiplayer.dll.verify that you have access to that directory." I tried to uninstall but it brings up errors. I have tried to install again but it brings up errors. I don't know much about computers so any help would be greatly appreciated. This just started the other day. I haven't had problems in the past. Thanks

Hello Judoh,
I recommend Uninstalling iTunes and then re installing it.
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

I can´t open iTunes - error AVFoundationCF.dll

I can't open iTunes on my PC. What should I do? - error AVFoundationCF.dll

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. Now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair".
Does iTunes launch properly now?
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post:

I have uninstalled and installed itunes a number of times and I continue to get the same error message - making it impossible to open itunes on my Windows 7 pc. I have run out of my bag of tricks. How can I once again get itunes to run and work to access songs and connect my apple devices?

This also 100% work
Removing and reinstalling iTunes and other software components
If applicable, disconnect any iPod or iOS device and close Microsoft Outlook.
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 (see note 1 below)
iCloud (if present)
MobileMe (if present) (see note 2 below)
Bonjour
Apple Application Support
Reboot your computer. Delete any of the following folders where they can be found: (see note 3 below)
C:\Program Files\Bonjour
C:\Program Files\Common Files\Apple
C:\Program Files\iPod
C:\Program Files\iTunes
also on 64-bit systems:
C:\Program Files (x86)\Bonjour
C:\Program Files (x86)\Common Files\Apple
C:\Program Files (x86)\iPod
C:\Program Files (x86)\iTunes
Download the iTunes setup file and run it to install. Use an account with administrative rights. This can usually be achieved by right-clicking on the downloaded file and selecting Run as... or Run as Administrator. In some cases a combination of Shift or Ctrl keys may be required for the option to show, or it may not be necessary.
If you deleted iCloud and reinstalling iTunes doesn't automatically reinstall it visit iCloud Control Panel.

Hey bcolden,
I would try uninstalling and reinstalling following the directions in here:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
http://support.apple.com/kb/HT1923
This section in particular contains important information in the uninstall process:
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Important: Uninstalling these components in a different order, or only uninstalling some of these components may have unintended affects.
Let us know if following that article and uninstalling those components in that order helped the situation.
Welcome to Apple Support Communities!
Best,

iTunes auto-update dowloaded and installed on 28/01/2014. iTunes now won't launch and error message states file MSVCR80.dll is missing. Tried unistalling and downloading/installing again to no avail. Any clues?

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

When trying to launch ITunes I get an error message saying that application fail to start because MSVCR80.dll file not found. Reinstalling app may fix problem.

When trying to launch ITunes I get an error message saying that application fail to start because MSVCR80.dll file not found. Reinstalling app may fix problem.

I've just (finally) managed to fix this problem today. I checked the Apple Support forums, and it seems a lot of people are having the same problem.
I rang the Apple Support line, and the very helpful man (thanks Alan!) talked me through it stage by stage. If you go to the following page on the internet: http://support.apple.com/kb/TS5376 it takes you through the process. WARNING - it takes a little time!
Basically, the first thing you have to do is go to your Program Files and double click on your iTunes folder. There'll be a number of files with the suffix .dll - you need to move all the .dll files from that folder to your desktop - you can simply click and drag them on the desktop..
Next, uninstall iTunes - go to Control Panel / Add/Rempve Programs and when the list comes up remove iTunes. This will take a few minutes... Then reboot your computer.
Next, go back to Control Panel / Add Remove and Remove - IN THIS ORDER -
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support
Reboot again!
Next, check in your Program Files that the iTunes folder is completely gone - if it has, great: if it hasn't, right-click on the folder and press Shift and Delete - it will say "Are you sure you want to completely remove the folder "iTunes"? Click on "Yes".
Reboot!
Then go to the iTunes download page and voila! It should download iTunes without any problems... well it did for me.... Good luck!

ITunes error 7 (windows 127) VideoToolbox.dll

I have uninstalled, reinstalled, tried installing the videotoolbox.dll file seperately, and looked up just about everything i can find but nothing matches my exact problem or fixes it. When I try to open itunes i get 2 error messages. The first reads:
"The procedure entry point kVTCompressionPropertyKey_ThrottleForBackground could not be located in the dynamic link library VideoToolbox.dll"
After I click ok I get another pop up saying:
"iTunes was not installed correctly. Please reinstall iTunes
Error 7 (Windows error 127)"
Can anyone help me fix this?
Thank you
P.S. I am running Windows 7 64-bit

For many of us there is an error when launching iTunes 9 - try this first.

If you are among the many that has the error about a dll file not found, you might want to look at this thread and try the reccomended fix (installing an update to directX).
http://discussions.apple.com/message.jspa?messageID=10400226#10400226
But BEFORE you do, make sure you aren't already using a version of directX that is higher than that shown (click start, run, and type dxdiag then enter. this is the directX diagnostic tool built into Windows.). The link in that thread is to Microsoft's download page for updating directX9.0c and all PREVIOUS versions.
However, if you're in any way like me, and have been maintaining your computer somewhat diligently, you are already using directX version 10. This fix probably doesn't apply in this situation, and needs further analysis from both Microsoft and Apple.
Good luck! Post your results, please, so that we can all benefit and resolve this annoying error!

Perform a hard reset on your iPhone (press the Home button and the Sleep to screen off)
Connect the USB cable to your iPhone and launch iTunes
It's time to position your iPhone into DFU mode (Device Firmware Update) how: Press the Home button and the Sleep for 10 seconds (remember 10 seconds!), After ten seconds, release the sleep button and press and hold the Home button for 10 seconds (if you do it all correctly and the time is right) then it will display a message from iTunes like this.
If you do not get a message like that, repeat step 3, until you get a message like the above on your iTunes.
After step 3 successfully, iTunes will start restoring your iPhone firmware to its default alias originis firmware
After the restore process is complete, your iPhone will reboots and if your iPhone is connected to iTunes, so flame, iTunes will offer the iPhone restore from backup that you created (which will restore the contacts, music, video, photo, and application), if you previously never backed up your iPhone, you should select this option.
The process of backing up restore your iPhone will take approximately 2 to 3 hours, so you should be patient.
Once completed, iTunes will inform you and your iPhone will reboot again
The next process, sync your iPhone your iTunes, if the iPhone has been running with the normal synchronization process would not be a problem.
Congratulations, your iPhone is running normally again.

Can't launch iTunes due to a missing MSVCR90.dll file

iTunes system error. When I try and launch iTunes get the message "The Program can't start because MSVCR90.dll is missing from your computer. Try reinstalling the program to fix this problem." Then it says Error 7 (Windows error 126)
My specs are Win7 64
I had no problems with iTunes since I built this computer 6 months ago. I tried opening iTunes today and poof! it doesn't work.
What I have tried so far: I did a system restore. I uninstalled and reinstalled iTunes multiple times. I did a virus scan: Came back clean. I disabled my firewall settings and uninstalled and reinstalled program and tried to launch. Same error. I did a disk scan on my C drive. I did a registry cleaner with CCleaner. Not sure what else I can do. Any suggestions?

No one else having this problem?
