Hello
I think I found some errors within the Lukla Mt Everest add-on, which cause the described misbehaviour (error messages, crashes or the airports and scenarios are not found at all).
Error 1: The path to the uninstall file is incorrectly entered in the Windows Registry. The backslash between the scenery folder name and the uninstall file name "... sceneryuninstall..." is missing.
Error 2: The system requirement was specified incorrectly. According to the specification 2 GB Videoram Garfik card. However, the Lukla scenery in some areas takes 3.9 GB so just under 4 GB Videoram in the highest resolution. Unfortunately, this significant additional demand beyond the given specification is also not monitored or intercepted, which then leads to an immediate crash and freezing of the PC, if the graphics card has only 2 GB Ram.
Error 3: If the default installation path was changed during the Aerofly setup (i.e. the default path was not used), Lukla does not install itself in an addon directory for Aerofly but inexplicably under the Scenery main directory. Although Lukla seems to pick out the correct path of Aerofly from the registry, the installation then takes place in the wrong directory. As already written in several Aerofly forums, you should never install addons directly under the main scenery directory of Aerofly, because then it just doesn't work properly.
It would be nice if moderators or admins who have contact to the company of the Lukla software could pass this on, so that appropriate corrections are built into the software. I don't want everyone to spend hours finding causes for bugs in purchased software like I do.
Thanks
