Several errors: missing MSVCR80.dll, "Service 'Apple Mobile Device' failed to start", Error 7

I have been trying all morning to re-install iTunes, but continually receive the following errors:

"Service 'Apple Mobile Device' (Apple Mobile Device) failed to start. Verify that you have sufficient privileges to start system services."

"iTunes was not installed correctly, Please reinstall iTunes. Error 7 (Windows error 126)"

"iTunesHelper.exe - System Error: The program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem."

I have found a solution on iTunes support for the Error 7 message and followed the instructions, but the problem was not resolved. I have uninstalled and reinstalled iTunes several times (I am doing all of this through the administrator sign on on my Windows 7 PC), and still receive these errors. I have purchased a registry cleaning tool to try to fix the .dll error and it was not resolved. I can't even get iTunes to install properly on my computer and have lost all use of the program. I am at a loss as to what to do!! Can anyone help!!

I am getting the same error message - error 7, Windows error 193 running iTunes on a PC Laptop (HP) which has been running iTunes previously for at least 2 years.

I followed the Apple support page and uninstalled (in order) all Apple programmes specified, rebooted, then re-installed. Two additional errors crop up in re-installation, the first one is to do with Apple Mobile Support Device Services. It seems that this might be rectified by plugging in said devices before finishing the re-install. The second reads iTunesHelper was not installed correctly please re-install iTunes. This persists. I cannot uninstall iTunesHelper using the Control Panel, but I can delete it using Windows. However, after re-installing again, it still won't run and the original error comes back. I've downloaded and uninstalled 15 times now and this is taking far too long to be acceptable.
