Perpetuum

Quick fix; disable 'Advanced Features' and you're good to go for now.

I haven't tried it while other products were installed. However I do advise you to to first just uninstall the 747 and give it a go. It would be a shame if you'd uninstall any products unnecesarily.

Hi guys,

I also encountered an issue with FLEXnet where it was not installed at all (should be in c:\program files (x86)\common files) and there was a false entry in the services.

I'm not sure what corrupted FLEXnet, but after about 2 hours of trouble shooting this worked for me:

First of all, make sure you do not have the 747v3 installed. If so, make sure to remove as admin.

1) Open commandprompt as admin (important!).

2)  type sc delete “FLEXnet Licensing Service”

3) Next, turn off all anti-virus software and firewalls (worked for me) and download the installer

4) Install PMDG 747v3.

If all went well, you'll now have a valid FLEXnet installation and a clean entry in services. If so, you're good to go and activation should work.

There will be volumetric lighting included but the beams won't reach beyond the cockpit, so you won't be able to observe this from inside the VC.

Hi all,

I'm experiencing a performance drop using the 737 immersion effects.

Performance may drop about 60% from a stable 60 fps without active effects to only 15-20 FPS with effects.

This drop happens with volumetric lighting and wing condensation. All other effects work just fine and without any impact.

Will there be something wrong with my settings? I've tried reducing Special Effects from 'High' to 'Medium' but no noticeable changes there.

I run Prepar3d V3.2 on Windows 10, i7 6700K @ 4,4GHz, 16gb RAM and a GTX 970.

Any help will be highly appreciated!

P.s. this also happens with the other immersion packages I've installed.
