    Can't install, uninstall programs or updates/drivers


    Very weird. I am running Windows 8.1. The other day I come to find my nvidia and Bosto drawing tablet drivers hosed. I proceed to try to install new ones which seemed to work. I noticed when trying to run Windows update it hangs on installation. Then it seemed to apply to almost anything. In other words, my OS runs ok, programs launch but I can't install or uninstall anything. I thought it might be the Windows installer so I ran the MS online fixit. I also ran MSIExec /unregister and MSIExec /regserver, Still no good. Avira, Malware bytes and Kaspersky's rootkit scanner come up clean.

    Out of desperation I put in my 8.1 disk and ran the inplace upgrade which created a new Windows directory and everything. Although it retained my setting I still cannot install or uninstall anything. I know I can rebuild but my inner nerd is so lost on this I feel like I need to fix it. Any thoughts?

    Wow, I found this thread here and fixed it:
    error 1719 windows installer service could not be accessed .... - Microsoft Community

    Start, then Run, then type regedit Go to HKEY_LOCAL_MACHINE\SYSTEM\CURRENT CONTROL SET\SERVICES\MSIserver\WOW64 Right click on WOW64, then select Modify Set Value Data to 0 (mine was set at 1) and Base should be Hexadecimal Close everything, reboot, and see if you can uninstall or reinstall
    Now for me I did not have this key so I created it, bounced the PC and everything is working. How crazy is that?

    I just tried creating WOW64 both as a binary and a string value in regedit and setting it to 0 but I still can't install cygwin and the latest firefox 35.0.

    Note: I'm a Linux guy so my Windows is rusty but my msiserver entry was all lowercase and not MSIserver. Has Windows become case sensitive?
