I've had this problem for about a month, and every time I fix it in a new way, it keeps coming back a few days later. I've restarted my modem, restarted my computer and updated my drivers. Sometimes...

Thanks guys! Will follow up with the steps.

EDIT: Forgot it was a big file. Will leave it to download overnight and hopefully fix this problem once and for all tomorrow. Appreciate all your help...

I read it, however I still don't understand why the command prompt says it could not find the source files. Where is this source file located?

Stuck at this step. Not sure where/what to do with the "source files"?

Doing now. Thank you so much for your help so far.

Thanks for the reply. I did as you recommended, and this is what I got:

It says Windows found some corrupt files, however it was unable to repair...

Recently, I've noticed that some the right-click menu bar icons haven't been appearing, among in some other places.
