Noticed a possible lighting issue with OIIE purchased through orbx. Here is the thread I started there - https://forum.orbxdirect.com/topic/222621-homa-sim-oiie-missing-files/
John Burgess, always helpful, said he was seeing the same on his install. It could be that the 1.1.4 files supplied to orbx are at issue, but can't be certain. Anyway, thanks for your support/ideas to get it sorted!
Happy to attach the images on the other thread here if you prefer.
Hmm..there was a problem some time ago, when MSFS failed to launch some applications via the exe.xml file, but I thought they had been resolved by Asobo. So far, I can only advise you to continue as you do now, that is starting the driver manually. If anything further comes up in the future, we can come back to the issue.
