Recently when trying to install software I keep getting an error message in windows installer that says "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows installer package." I have done a virus scan using up to date defenition files and it doesnt find anything. How do I fix this error?
Click Start, and then right-click My Computer. On the shortcut menu, click Manage. In the left pane of the Computer Management window, click Services and Applications, and then click Services. In the right pane, scroll down to Windows Installer, and then right-click Windows Installer. On the shortcut menu, click Start. or set it to manual if disabled
In the Start Menu select Run, type cmd, and then at the prompt type msiexec /regserver
