just tried to install Infinity V 1.0 in an Empower3 environment (W2K8 R2 server, XenApp6)
It failes with an error "WIDS_SCR_CANNOT_LAUNCH_SETUP".
On a LACE (Empower3, Win7) it also failes with the same error.
I remember similar issues with other ICOPs in Empower3 due to a "old" version of the Windows installer. I'll try to get mor info.
