How can I repair CIS?

How can I repair CIS? In Control panel Add/Remove Programms the repair option is greyed out and it is written CIS Premium can not be repaired ???

Have you tried opening CIS and going to More => Diagnostics?

Please see if the diagnostics can fix whatever problem it is that you’re seeing.

Diagnostics shows no problems.
Repair option grey is not normal , right? What to do?

Hi cska133,
If this is the only symptom, I say it is no call for concern.
My repair option has always been greyed out (CIS Premium can not be repaired), my guess is this is normal unless a problem is evident.

What if any other symptoms are you getting to make you think it needs repairing?
Kind regards.
