msinstaller 1015 won't work at all, can't install, can't uninstall.

Also got "Failed to connect to server, Error 0x800800005

What is the best option to fix this problem?

Hi ComputerWhizz7, I guess some of your services required are not running. Alternatively U can also try to run some malware and virus scanners to determine if your system is infected.

Below is a link on the error U had stated, hope this does help...
