Hi,
Thanks for your information.
Vugen 11.52 does support Citrix client 10.2. Please refer attached vugen11.52 image.
However, in BPM support matrix, BPM 9.23 only supports Citrix client version from 14.x. Please refer the attached BPM image.
So could you please upgrade Citrix client to version 14.x and try again?
As the issue only happens in BPM so you should post a thread on BPM Forum for better support.
Regards,
Chau
