Hi Pete, Hi Dennyrambow ! You can't know how happy I was when i found this topic ! I just bought P3D V2.4.1 and after installation of Ivap i had the same issue than Denny. I tried a lot of times to uninstall and reinstall one by one all of my add-ons and confirrmes that the problem comes from FSUIPC, v4.938. I started to loose hope, and trying last reseach on the internet but i was alone in this situation ... So i found this topic and hope came back ! But i am a frecnh student and my english is not as good as yours ... So i didn't understand everything in you explaination :( I would be very grateful if you would explain me again what i have to do to solve this problem ... I work on W8.1 with P3D V2.4.1 and want to install a lot of add-on :p Thank you for your amazing work Pete, And i thank you in advance to help me ! Best regards, Côme.
