Configuration Windows 7 X64, 6G Tri-channel memory, Nvidia 800 gtx 650 watt P/S. 2 500g RAID 0, MSI platinum mb.
Ran the usual memory test from the install DVD no errors. stable system.
No errors I could find in the event viewer applicable to runing the installer.
Ran the SFC /scannow option
Ran chkdsk /f on the c: drive. fixed errors the first time.
Decided to remove one application at a time.
Instead of firing up process explorer. I decided to do some old fashion detective work and remove a program at a time.
The first one on the list was 7 zip. removed both x32 and x64 versions. The x32 version I remember was 9.20.
Ran the Nvidia driver installer for 260.xx (something). OMG. it works.
Something about this version of the third party program was interfering with the setup up app.
Was able to run the setup directly to confirm the cause and fix. both prior to removing 7zip and post removal.
If you find this helpful then please post your agreement or comments!
Probably would have been easier with process monitor or re-installing, but wanted to sharpen my old fashion skills learned back in the 80s.
