I'm developing on Windows 2008 R2 Server, 64 bit.
I'm learning how to use gacutil.exe
I found two copies of this file:

```
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\x64
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\

```

I built a dll in VS2007, then I added a build post event, that calls gacutil.exe to transfer the dll to GAC.
Does it matter which gacutil.exe I use?
