Sorry - but this is rubbish.
It's not.
I have seen plenty of messages on this forum where it looks like the Administrator is getting frustrated over this question, and generally comes back with 'we've already answered your question'...
I usually always include a link to previous messages that discussed and answered the same thing.
Because I had a slow reply from you, I went to another forum to try and get help.
You went on Avsim forum a few *hours* after you posted here, without even realizing it was in the middle of the night HERE! Are you trying to say that, unless we work 24/7, our support can only be flagged as "slow" ?
It describes how I fixed it and how annoyed at this software I still am. (Just to note, I have spent most of my life as a software developer, and I would NEVER write a piece of software that relies on the end-user being able to go into the file-system and have to make changes to file names, etc.) If you want your software to use another BGL file - write that into the front end!!!?
Sorry, but you are so wrong in this reply, that I don't even know where to start.
I'm not sure what kind of software you write but, I would NEVER write a piece of software that would touch any files belonging to OTHER 3RD PARTY PRODUCTS installed alongside the same host.
Because, if you haven't realized it, the simulator is a host, and what you are installing are, essentially, 3rd party plug-ins that CAN have conflicts between each other but, if would be WRONG, WRONG and WRONG AGAIN, if one of them tried to fix conflicts in OTHER files not belonging to itself!
In any case, I can see plenty of replies on Avsim too to the same message you posted here and, guess what, they are all saying the same thing so, maybe, it would be best if you reconsidered what you said.
