Loss of Word & Excel

LOSS OF WORD AND EXCEL MacBook Pro 8.2

It seems more than a coincidence that after signing up for MacKeeper I have lost access to both Word and Excel.

Any advice on how to UNDO MacKeeper would be much appreciated.

MacKeeper is pure garbage, snake oil. In order to completely remove it from your Mac, please follow these instructions: LINK

And, please do not install any other so called cleaning utilities on your Mac. The only maintenance utility we recommend is OnyX which is safe and will not do harm to your Mac.

Also, please follow the Microsoft instructions for reinstalling Office on your Mac. Since you didn't say which version, I can't direct you to the link.
