I have encountered a strange issue involving the attempt to install one particular PC utility - Slim Drivers. It is a freeware product that handles driver updates and seems to do a fine job on another of my systems. No problems installing or using it.
However that is not the case with the ASUS All-in-One PC/Tablet (model# P1801) that I am currently attempting to install Slim Drivers onto.
Whenever I begin installation (I install as Administrator) the install proceeds to about two-thirds finished approximately but stops and then gives me the following error message:
Key Not Valid for Installation In Specified State
and the installation says that it has encountered an error and must stop.
I used System Restore to roll back a week but the problem still continues.
As I stated earlier I have never had this problem with any of my other systems - just this one.
