Often it’s useful to have assembly files added to the Global Assembly Cache using a command-line (DOS-style) batch program - eg. install.bat

For Visual Studio 2005, this file (GACUTIL.EXE) is located here…>

C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin
So, for Visual Studio 2008, I had assumed it would be in the same location - or even in the new v3.5 folder…>

C:\Program Files\Microsoft Visual Studio 9.0\SDK\v3.5\Bin
BUT - it’s not in either of those locations, and (after some hunting and Google’ing - and not sure why), but I found it here…>

C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin

NB. This is for a Windows Server 2008 implementation - a quick check onto a Windows Vista (x64) machine verifies has the same file location.
