My new-built Win10 confutor is up and running and I'm installing my FS software. I've run into a problem with ADE9X, a program I use regularly and would be lost without.

I downloaded the latest release version and when I run the installer I get a message that the program installed successfully. But when I try to open the program I get an error message:

"ADE has encountered an error in loading.
This error will stop ADE from operating correctly.
It will therefore close when you dismiss this message.
The error encountered is shown below. If this persists
then please report it via our support forum at
www.fsdeveloper.com. Thanks

Access to the path 'C:\MSFS\FS Design Tools\Airport Design Editor
9x\fs9\plugins.dat is denied"

I went to the referenced forum and found no thread that seemed appropriate to search for or post about the problem except perhaps the Comments forum, which is a locked thread. I've e-mailed Jon but remarks on his web site suggests a replay might take a while.

Has anyone else run into this problem? If so, did you found a solution?

(I'm going to cross-post to the FSX forum just because there are no many more participants there.)
