Dang..

thanks!
So I have it all working successfully!
FOR /R D:\Infragistics\ %v IN (*.dll) DO D:\Infragistics\Gacutil.exe /I %v
Though I am still having troubles with the output. If I output to a file, it doesn't get written there. If I put standard output, it only works 1/3 of the time.
Thank you for the quick assistance on this. If you find a fix for the output, please post.
cheers.
