Act Premium Web v17 - IIS Corrupted/Lost

[Andrewmanning84]

I have Act Premium Web v17 with latest SP on Server 2012 R2.

IIS got corrupted and only way I can get it working is to remove and reinstall. But this will lose all the Act IIS integrated websites etc.

What is best way to proceed?

Should I backup DB, remove IIS, remove Act and then start again. I have to do it on same server.

Reinstall everything to same locations, restore DB and clients should not be affected?
