I'm running Windows 7 64 bit, and I've run into a problem with Windows Installer.
Whenever I try and install or uninstall a program, I get a message that "another installer is already running, please complete the installation and try again".
But I'm not doing another installation.
This has meant that I can't install updates on a number of things....Java, iTunes, Adobe Acrobat, etc.
I've done some searching already, and found that by right clicking on Computer in my menu, I can "Manage" it, then go to "Services and Applications", then "Services", go to Windows Installer, and disable it. If I reboot, I can then go back to the same screen set Windows Installer to "Manual", and it will work. For one install or uninstall. Then I have to do the whole thing all over again.
This is obviously not a workable solution longterm.
I then downloaded FixCleaner. I tried the 1 click fix, and it seemed to really speed up my computer....but it also messed up my registry by seemingly deleting drivers
etc. as programs like iTunes stopped working correctly, claiming that the registry values for drivers used for importing CDs or DVDs were missing.
So, I did a system restore, to the point before I did the one click fix.
I've now got a system that can't install or uninstall any programs without disabling Windows Installer and then rebooting first.
How do I fix this problem? Is there a way to install a fresh copy of Windows Installer?
I've tried going into Task Manager to see if I can find other programs trying to install themselves and hanging, but I can't seem to find anything.
What do I do?
