Out of curiosity, I tried NOT running X2 as administator just now, and Pentagon comes up on the saved file as a "missing plug-in." So, for me, I have to run X2 as adminstrator... I have also had audio engine craashes (i.e. not work at all) for X2 that also went away when I began running as administrator. I need more data on the audio engine to confirm that the run as administrator fixed it.

Running with administrator priviledges helped. Actualy I heared mu Pentagon I for the first time :) Thx!

Hmm.

Pentagon runs perfectly fine on my DAW, but on my other machine which is running X2, it's telling me the synth is not installed properly.

I just tried installing it again and the installation aborts with a "code 5"error, whatever the hell that is!

 Code 5 errors often refer to permissions issues.....

Well, this thread dates from a while back, but I'm happy to report that Pentagon no longer causes me any problem on any of my 3 systems.
