*Repair Windows Installer Service in Vista (All Versions)*
For all those unfortunate souls searching and Googling for how to
repair the Windows Installer Service, I have some info for you. A couple
days ago I tried to uninstall one of my apps and stalled on an error
"Windows Installer Service cannot be accessed". After many trials and
errors trying to fix this issue I stumbled upon a new fix for this issue
that has worked in all these situations where the Windows Installer
Service will not manually start, and in essence not allow install or
uninstall tasks to complete.
1. Go to a Windows Vista*(any version)* computer that has the Windows
Installer service running correctly and run
2. Go to the location
3. Right click on this key and select "Export" and save the key to a
Flash Drive or other.
4. Double click saved .reg file from working machine and import
registry settings into damaged Vista computer.
6. You may need to go back into services after the import and start
the Windows Installer service and set it to automatic.
7. If you can't get your own reg key from a friend running Vista then
you could try and use the "clean reg key I used" download here:

If you have success with this method please post this fix around the
WWW as I went through over 1000 links with users having the same problem
and not being able to solve it. Shame on Microsoft, very sloppy. It
would have been so nice if Microsoft released Windows Installer 4.0 as a
standalone installation with Vista's release so I could have repaired
it, most users have been doing fresh installs to fix this.
