Windows 7 environment is very new to us and having a problem installing Client 2 SP1 - IR7. Install stops when unable to find/access "nccredlogonext.dll" when installing from CD or HD.

Doesn't seem to be a download/Hash issue as the overall download file checks out Hash-wise. The path containing the file in question is:


Not sure why "amd64" is involved although the machine is a Precision T3500 with Intel Xeon 64-bit on Windows 7 SP1.

It's all brand new to us so any help would be appreciated.
