I am running Vista Ultimate.Yesterday I began experiencing video problems
with MS FSX after installing Nvidia Driver version 158.18. I uninstalled the
driver and the Game. I then went to run a Direct X check @ RUN>DXDIAG. I now
get an error message that "dxdiag.exe is not a valid Win32 application" What
happened? I cannot even open the program directly from System32 folder.
Anyway to fix this, or get it back? Does this mean I have lost Direct x 10
from my system? Thanks. Mike.
