Hi John,
Yes I only tried creating the AppData\Roaming\Microsoft Flight Simulator folder as you had suggested it as a possible fix for the installer not writing the EXE.xml. Like the others I tried that and the installer still did not create the file. Was just pointing out that fix didn't work for me either.
Yes, In step 8, I had the EXE.xml file in both LocalState and LocalCache folders.
As I don't have a full understanding of the file structures I wasn't sure what should be where so I tried a few things. My UserCfg.opt is in LocalCache so that would be why it works. I don't have that opt file in my LocalState.
I'll report it to Aerosoft for sure, but would like to see confirmation from anyone else that they also had installed the Honeycomb software first as more evidence would be helpful just incase it might have been something else.
Hope this has been helpful.
