Windows installer service error

[Sven]

I can't install or uninstall anything more. It has been running just fine, but suddently I get this error when trying to install or uninstall:

The Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed.

How can I correct this?

Try this...

Go to 'Start'
Enter 'Run'
Type: 'msconfig'

Make sure it is set to' Normal Startup' on the general tab.

I changed this by mistake and had this problem.
