Windows 7: Win7 Windows Installer issues

03 Jan 2010   #1

Win7 Windows Installer issues

  • I can't back up my data. I don't have anywhere to store 450g+.
  • I'm on Win7. (An RTM version)
  • MS doesn't offer a Windows Installer 5.0 Installer/Repair utility.
  • Trying to use an older distribution (4.5, anyway) tells me I'm using an incorrect OS.

Deleting the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions stuff, and turning off the Customer Experience Improvement Program Client thing didn't work either.

I can't install or uninstall anything using Windows Installer, obviously.
I need a solution.
The easiest thing I can think of is if someone can give me an archive of the Windows Installer files and registry keys (And a .txt of everything's location) for Win7, and I can replace all the ones that I have. Though, I don't know if all of the keys and files are known,

Can you either, you can try safe mode if necessary, from an administrator account type cmd in search and then in cmd type sfc /scannow. You may have to try it several times. A report should be generated explaining the problem. It will fix one problem at a time, so several passes may be needed.

Repair Windows Installer Service in Vista (All Versions) - Vista Forums

Just replace any Vista Reference with 7 and see if this works.

Here's the easy steps:
1. Go to a Windows Vista (Any Version) computer that has the Windows
Installer service running correctly and run regedit(Start-Run-Regedit)
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. Run sfc /scannow on the damaged Vista computer - you won't need the
install disk as it goes to backup files on your HD. Do not reboot when
5. Double click saved .reg file from working machine and import registry
settings into damaged Vista computer.
6. Now reboot and try to install/uninstall

Here is a 7 msiserver.reg key
Copy and Paste to Notepa and save as msiserver.reg
then double click it....

Having a similar issue, have tried everything without success. I opened a thread in another sub-forum, in case you want to try the same fixes I have. Please let me know if you find the solution, I'll do the same.

Good luck.

The SFC didn't work. I just gave up and did a repair/upgrade install. It's working now.

I'm worried however, because I have 15gigs more than I did before, and I can't help but worry it reappropriated space from somthing of mine. With 400g+, it'll take forever to find out.

EDIT: Forgot to thank everyone for their time and suggestions, so Thank You.

That 15G may not be from losing data. It could be,,, from missing windows updates, as well as software that may need reinstalled. There is also a folder called winsxs that can grow and will over time,,, System Restore Points could have been cleared out an restarted. There are other explanations as well.
