It's been a nightmare since late yesterday. First thing that happens is when I booted up Window Media Center to watch the Rockets, may PC basically tells me I have no TV tuner card. No big deal. I'll just get a new card. Whoopee. I reboot the PC to see if that would resolve it but I keep getting registry errors back-to-back-to-back on startup, even when booting in safe mode. Finally it boots up in safe mode and I'm able to do a system restore to 6 days ago. Everything seems to be OK. When I turn it off for the night, I noticed the shut down button says "Install updates and then shut down your computer". But unfortunately power is shut off to the PC before it completes the shutdown. I'm too tired to care so I go bed. When I wake up, it boots just fine, but when I boot up any MS Office 2010 application, Windows Installer comes on and won't let the application finish starting, even when I hit cancel Windows installer. I download a couple of "registry cleaners" that do nothing to solve the problem. To make a long story shorter, I'm able to boot up Word and Excel in safe mode without Windows Installer getting in the way, but when attempting to open any files, I get the message the file is corrupted. Outlook will not boot up even in safe mode. Anybody else been through this and solved the problem? I'm bummed out big time. P.S. I went to System Configuration, the Startup tab, unchecked Windows Installer and rebooted. Still couldn't open any MS Office applications because Windows Installer was missing (or something like that). Chrome works fine. Windows Media Center (now) works fine. Quicken works fine. Star Office work boot either because of W.I. HELP!!!
You accidentally shut off the power while it was installing something last night? Could you try restore (again) and reinstall Office?
Have you tried a 'repair' installation of Windows? I think that is one of the options when you insert an installation CD.
I would lose all files and programs and the PC would revert back to exactly as I bought it. I'll do this if necessary but wanted a less radical option.
Repairing a windows installation is intended to replace the system files, but leave your applications and data intact.
I'm going on a different track now. Anybody know where I can get a copy of trayapp.msi, which is what Windows Installer is asking for every time my PC boots up? It's not on my HP printer CD. I can't find it on HP's website (so far).
Try these HP instructions. They are generic to *.msi errors, but the page that got me there was specific about trayapp.msi. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01631295&cc=us&lc=en&dlc=en&product=3390947
Been directed to this page many times. But after downloading the "full feature software and drivers" for my particular HP printer, trayapp.msi is nowhere to be found.
I was able to find the trayapp.msi file from the download but Windows Installer didn't accept it as the solution.
That so sucks. Did you see the site called http://www.trayappmsi.com/ I'm not so sure I'd trust that site...but if you are at a last try state of mind before doing bobrek's suggestion, why not? I think I'd probably go with bobrek's suggestion, just suck it up.
