dbd_oci.dll not valid Win32 app on Citrix

Hi guys,

I have SAP BO 4.1 SP5 Client Tools on Windows Server 2008 R2 running Citrix. Oracle12c 32bit and 64bit clients installed (32bit is first in PATH ENV).

When users run Webi Rich Client, IDT using Citrix and try to get data, only thing they get is error dbd_oci.dll not valid Win32 app. (IES 10901). In case I log to server using RDP and I try same things as users (refresh data from oracle), everything is fine.

Any idea what should i check?

I will realy appreciate your help.

T.
