Jeffrey,

 I am running Windows 10 Education on x64 architecture. The version of the
AFS client I am installing is 1.7 provided by YFS.
*yfs-openafs-en_US-AMD64-1_7_3301.msi
*I've installed it along with one dll file - afscreds_1033.dll. But thanks
to the information you provided I was able to get it running.

Thanks for your help,
