Another installation is in progress
- by Steven
Why I try to install any program I see "Another installation is in progress. You must complete that installation before continuing this one." error.
Googled the web and found that solution would be to delete
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\InProgress registry key and reboot.
That didn't help me unfortunately. When I open "Services" mmc snapin it shows that "Windows Installer" service is "Started", but "Start/Stop/Pause/Restart" buttons are grayed (the interesting thing is that startup type = "Manual", so I don't really know how to explain that I already have 2 instances of msiexec.exe in memory and one instance is consuming 50Mb of memory.
Looks like there's a serious issue with my installer service - is there any way to fix it (please do mind - I can't install anything!)
Any help would be greatly appreciated.
