Windows 7: Windows Installer/Error 1721

Windows Installer/Error 1721

I was trying to install my graphics suite on W7 and got a error message that say 1721 and something is wrong with the windows installer. I've already tried system restore and that didn't work out. I also tried re-registering the windows installer and running the system file checker and there was no problems.

Where's the fix for this? I need it bad.

Are you installing a 64-bit software package on 32-bit Windows 7 ?

I'm not sure what bit the software is but, the software has been running fine on my system until yesterday I had to modify it and it wouldn't let me. I also tried uninstalling and repairing. None of those worked so I got the Uninstall Tool & deleted it out my system and now I am getting that error msg below.

Windows Installer kept having a problem and looking for msiexec on my backup drive. I went to regedit

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msiserver or use Edit,Find to search for msiexec. Edit the ImagePath by right click and Modify.

@SystemRoot%\system32\msiexec /V to c:\windows\system32\msiexec /V and voila, no installer problems.

Are you running the installer as Admin?

Establish a Clean boot and look for other clues in these Troubleshooting Steps for Windows 7

If steps fail try the Repair Install or get a perfect baseline Clean Reinstall with backup image made after setup you can use to fall back on in the future.
