I just tried rebooting and tried it again and get the same error message. I am at a loss of what to try.
I am trying to install 20211029 to 20130415 in FSX, Windows 7. I am getting error, " Can not upgrade due to Not Enough Disk Space." I am migrating to the REX Essentials Folder and I have 2.7 Terrabytes on my hard drive....that should be enough. Any ideas?
