Thank you for the quick reply.
I recently checked the citrix website for the receiver for another project. According to the Release Notes it supports now 64 Bit without 32bit compat libs / Multiarch.
citrix.com/downloads/citrix ... -13-2.html
"Full 64 bit support, now includes the HDX Session technology. The whole 64bit package is now built 64bit, so no longer requires 32bit compatibility libraries to be installed on x86_64 platforms. (Session Launch Technology was supplied as 64 bit in 13.1)"
Could you please reconsider your stance on 64bit UCC ?
