I haven't deleted any folders. I was advised to install into the Custom location after choosing Default. This installs the plane into F:/ Just Flight/ BlkSqu etc. Then I was advised to copy that blkSqu folder and paste it into my Community folder for MSFS 2024. Fair enough, the plane is now installed. I can uninstall using the Windows Control Panel, but it won't uninstall the plane from my Community folder. I must do that manually. Can you see how much of a faff this is. I was also advised to delete the Just Flight folder which the installer created. However, if I do that, the Uninstall from Control Panel will fail and then my registry is going to be out of sync with my installed programs. Most addons these days can find your Community folder without any problems. I just feel a smarter installer would do a better job with such a high quality addon. Patching the Amphibious version is going to be a right PITA if I can remember how to do it in a few months time. I hope a better installer is built for this addon.
