Hi everyone !
I wanted to share that if you use the Citrix PVS install media 7.1.1 and that you need the local SQLExpress, THEN install it FIRST !
I did three test so far, the setup does not prompts any error if you select to install it, but it’s missing in the end.
You will see that you CAN’T install it afterhand. It seem to leave a corruption in the operating system.
So, install it before installing the PVS !!
