Oh dear!  Just back into P3D after 6 months out, and hit my 1^st major glitch before even launching sim:-(

As my P3Dv4 was several versions out of date, I decided on a completely fresh install.

Did it by the book.  Uninstalled everything first, then deleted all remnants in the ‘users’ folder.

All went well until attempting to launch, then it just sat there hanging at the opening splash screen.  Left it doing that overnight, thinking it might be indexing the scenery file, but 9hrs later, it was still going.

Tried again with a fresh download. Same result:-(

Any ideas?

You might nevertheless consider in deleting the prepar3d.cfg just prior to the first start. Did you really delete all remnants on the C: drive? Appdata/Roaming, Appdata/local and all this stuff? Nothing left anymore with a orphaned add-on.xml somewhere?

It doesn't have a cfg file on first startup and doesn't get as far as creating one.  Definitely removed ALL trace of previous install. Done it many times.

Hello Phil

As part of the Uninstall process did you remove all 5 locations for generated files and folders ?

Have a look at this quick video,  Then launch Prepar3D and test
