I hate to revive an old thread but I appear to be having this "EXACT' issue in XenApp 5 on my 2008 Servers. I have added the Registry key but it doesnt seem to do anything.... Does anyone know if there is a similar registry key in XenApp 5 somewhere or if this reg key has been removed completely?
Same here. It is fairly intermittent but happens often enough. If i keep trying it'll eventually work.
Try a few of the fixes I detailed in this recent blog about why Citrix apps don't launch sometimes --> http://citrixtechs.com/blog/?p=47
