Hello folks,After an OS failure, I had to start from scratch and do a fresh install of os etc. I had/have FSX on a dedicated VRaptor -I had to do a repair on FSX to get it in the new registry. I have reinstalled REX / GEX / UTX / FTX sceneries and all work well.I did a uninstall with Control Panel for the JS4100 that still had folders in FSX on the dedicated drive. (I tried to do a reinstall, but the installer did not have the "remove button" that the readme knows suggested.So, after the uninstall, I still had the two folders in FSX which I manually deleted.I installed and it went well, but never asked for serial numbers etc.The JS4100 will load up in FSX, however, no guages work as they are just blank. It's almost like threads I've read with the demo or unlicensed version.I have tried this twice to no avail.Please, how do I get a good fresh install that works?You help is always appreciated.Tom

Tom, this looks like licencing service not running at all, try turning off your firewall and antivirus software, reinstall J41 and then try again.

Sawydz,I don't have any firewall running -I went to "event viewer" in win7 and it showed an "error in installing gauges"........I "do" have flex licensing running.Any other ideas?Thanks,Tom
