TestComplete cannot see a screen object's property anymore

I am trying to run a script on a desktop application (.NET), which worked previously in a private virtual machine, in a new, different virtual machine.

In the new one there is a screen object with a property TestComplete cannot spy, detect or use anymore. It could in my private VM.

Now, I have been trying to spot all the differences between environments. This is what I know:

- Same TestComplete version (11.11)

- Same TestComplete configuration

- Same script version.

- Same libraries version.

- Same application under test version.

The only possible difference is the Microsoft .NET framework version, but that is only according to the about section in the application under test, because when I check the Windows control panel they are actually the same.

Any suggestions?
