I have never used the tool, instead I have always used the manual process outlined on page #1 of this thread:
Download and extract the two updroots.exe packages (they are the same except for the inf files):
· updroots.exe [5.2.3790.4456]
· ADVPACK.DLL [7.0.5489.0]
· rvkroots.inf and rootsupd.inf
Tweak both rvkroots.inf and rootsupd.inf with:
· VERSION="5,0,2195,0"
· Ver="005" and Ver="040"
Download the latest .sst files (from http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/):
· disallowedcert.sst
· authroots.sst
· delroots.sst
· roots.sst
· updroots.sst
Use Rundll32.exe to apply the files:
· Rundll32.exe advpack.dll,LaunchINFSection rvkroots.inf,DefaultInstall
· Rundll32.exe advpack.dll,LaunchINFSection rootsupd.inf,DefaultInstall
This has always worked for me.
