Hello,
I purchased Parallel 42 - 42CM scenery for MSFS and noticed that it did not install correctly.
I did not install it directly to MSFS, but into my remote library where I have many other sceneries that work just fine.
Upon investigation, it seems that the actual required scenery folder was within another folder not allowing the symbolic link to function.
I was able to manually fix the issue but thought I would bring it to your attention.
