rundll can't load ctor.dll, access denied.

I'm trying to install Win 7 (from vista), using the toshiba upgrade assistant, and there are several 'components' that have to be uninstalled.

During the uninstall process, I get a pop up that says:

RunDLL, error loading ...Ctor.dll, access denied.

I tried using a different program (easy uninstaller) to take these programs out, but ran into the same problem with that.

How do I resolve this error and remove these programs?

Thanks,  Chris

Have you checked the attribute of the ctor.dll? It should only be
"archive" - and nothing else.
Also,do you have administrative privileges for uninstall ?
Also make sure the programs you are trying to uninstall are not running in the background (check services too).Disable all antivirus during the process.

According to scat7ter's advice in a Toshiba Support forum, the fix maybe as follows:-
"I finally managed to take care of the problem. This time I went to the Toshiba Resources Guide (icon on the desktop) Chap 5 Utilities>Toshiba Application Installer. This directed me to Start>All Programs>Toshiba>Recovery>Toshiba Application Installer>Next and picked the application."
