Unable to start Developer Studio in Arcade Showroom 11.4

Hi,

I noticed last week that OpenEdge 11.4 was available in Arcade Showroom to try out. I started up the preinstalled machine for 11.4 and logged in. But once there, I was unable to even start Developer Studio. When I tried, I got a dialog about not being able to lock ".file TableLock", and then nothing started.

This was the dialog:

Invalid Configuration Location

Locking is not possible in the directory "C:\Progress\OpenEdge\oeide\eclipse\configuration\org.eclipse.osgi". A common reason is that the file system or Runtime Environment does not support file locking for that location. Please choose a different location, or disable locking passing -Dosgi.locking=none as a VM argument. "C:\Progress\OpenEdge\oeide\eclipse\configuration\org.eclipse.osgi\.manager\.file TableLock" (Access is denied)'.

I noticed that the user Showroom only has read access to that directory, and in the 11.3 preinstalled machine, the same user har "Full control" of the whole C:\Progress\ directory hierarchy. Maybe the install was not done right in the 11.4 machine?
