Cannot Install Microsoft Security Essential, error 0x80070645
Hello,
My problem is with Microsoft Security Essential (MSE). I had some problems with Security Client while installing windows updates, which causes the updates not to be installed. Searching the Internet, I found that I have to re-install MSE. I tried to uninstall it. I got error about (epp.msi) cannot found, so I used "Let me fix it" tool from Microsoft to uninstall it. Succeeded to uninstall it, I tried to install it again; however, I got Error 0x80070645 [attached the pic.]
I hope you can help. Thanks,
