I can not install important updates. Anything I download will not install.
Error message is that
Windows Installer Services cannot be accessed. This can occur if installer is not correctly installed. Contact your support personnel for assistance
When trying to download important updates, install fails with error code
80070641 & error code
I have System Mechanic installed and evidently has removed my installer according to others sites I have been searching. So with this problem I cannot even download another windows installer and I am going to upgrade to Windows 7.
My question is will I be able to install 7 without this installer?
