We officially not support this, and we cannot simulate it as we don’t have such environment, as well it was never tested.
Said that, all our answers are guessing and officially not supported regarding this topic, please understand this.
Citrix User do not have access in installation directory in Citrix, this is a brake point. He need to do it with local administrator as rest will required changing windows registry’s and path to binaries where we not want to go… So unofficial I will recommend installing windows client with account who have access to Citrix installation directory.
As we officially don’t support it, this could not work.
Now why not starting to use the Ca Vantage Web Client instead. It will be easier and will work.
