Last week Friday, I had problems scanning from my HP6110, so I restarted my computer. When it restarted, it went into an automatic repair that said would take a "few minutes." After about half an hour, I tried to cancel the repair, but a message indicated it would not stop. After about an hour, I hard booted the system, but the computer would not start. I let the repair continue and was able to start the computer after two or three more hours.
Since that repair, I have been unable to open many programs, including QuickBooks (2010, 2011, 2012 & 2012 Enterprise), a tax program, IE, Kaspersky and iTunes. I am also unable to install windows updates, and get error code 80070641. Adobe Flash is not working. Kaspersky will not "turn on." (When the Windows update problem started, I also had error code 641. That is now gone.)
I cannot restore to a point where the computer worked -- the last restore I have is from after the problem. I have tried re-registering msiexec, run MS Fixit Install/Uninstall, Fixit 50809, Fixit Performance, Fixit wuRNP, installed and completed a Spybot scan (no problems), tried to install an updated Java (I can't listen to music via my browser because of a Java issue), merged the default .exe associations in my registry, checked my Event Viewer logs for issues when my computer went through repair, deleted every instance of Norton/Symantec security that I could find, tried sfc \scannow but got hung at 41%, completed chkdsk, ran Windows Defender quick scan and found no problems and a couple of other things.
Some programs work, e.g., Firefox, Word, Excel and Outlook. I tried to find something common between the non-working vs working programs, and the only thing I can see is that the programs that are not working are not showing up in my control panel.
I bought the laptop used, but the prior owner only used it about a dozen times. Prior to these issues, I was able to install, scan, print and open programs with no problems. I'm running Windows 7 x64.
