Are you doing an update or a fresh installation?
Why do you want it in an app stack? I think we tried originally, but then decided to just put in the parent images. I couldn't think of anyone we would have that we would want to restrict access to that application since they already are using the client to connect.
There used to be a blog article I references, but I can't find it any more, which explained troublesome applications and I believe the horizon client was one of them.
what Versions are you using?
I have the Horizon Client 4.9.0 packaged with AppVolues 2.14.
Only thing was I wasn't able to put it in the "basic apps" Appstack. I had to put it in a seperate, Horizon Client only appstack
I need this to be on an Appstack because I use it to direct connect to my image if I need to update it. RDP appears to be funky in many times and also sets my Sound volume to 100% all the time. If I use client I can preset it to for example 10 and it persists for clones.
I opened a ticket with VMware on it and it appears that the problem is AppVol agent version 2.15. Once we downgraded agent to 2.14 it worked like it supposed to.
