not a single thinapp will start properly

Hello fellow vmwarers (that a word?)

We have a nice VDI solution of VMWare and I'm trying to make thinapps but they all freeze upon startup.

The steps i take are:

1. on a thinapp vm i prepared (clean install, updated with windows updates) i run the VMWare thinapp application.
2. I run Prescan
3. I install & configure the application
4. I run postscan
5. I let the application built the thinapp
6. Copy the thinapp to network location
7. Connect to a VDI desktop
8. Browse to the network location of the thinapp and start it up

What happens next is really strange because it starts 3 instances of the thinapp (lets say Foxitreader.exe)

So in taskmanager i see

foxitreader.exe - normal amount of ram & cpu usage

foxitreader.exe - normal amount of ram & cpu usage

foxitreader.exe - higher amount of ram usage + 90% of cpu usage

But no foxitreader on screen.

Sometimes (not always) when i close 2 instances, the thinapp may suddenly start up.

Now foxitreader shouldnt be this resource heavy so I am really wondering what is causing this issue.

Is there a way to find out what is happening "behind the scenes"?

Hope you can help!

Tnx in advance
