It is solved. In the user directory was still a folder for Aris present. (empty though) After removing that one, re-install it, worked.
I strongly suggest to avoid such things as I already had twice a blocked application within 6 months. The solution is not something that standard users can perform.
I have the same problem, but can't run application till now. My steps are:
1. Start App
2. App runs download
3. App try to do some verification and error occur: "Unable to lunck the application."
Details (Lunck file):
I think I had the same problem on a Linux test system.
A setting in the Java Control Panel solved it.
Java Control Panel -> Advanced -> Security
Disable Mixed code verification.
I'm also having troubles launching the application.
Unable to run ARIS. Error while setting up the server environment.
Maybe this old thread can help you:
But somehow I doubt it.
I would reinstall ARIS Express.
I assume that you are working on Windows.
Delete this directory:
C:\documents and settings\<your username>\ARISExpress
Delete the cache in the Java Control panel. Hit everything so applications and applets are deleted as well. But be careful if you have other Java Webstart Applications installed!
Now install ARIS Express with http://download.ariscommunity.com/aris-express-setup.exe
Hopefully it will work then.
