Thanks for the help with the FAQ. I started over and downloaded new files and did a clean install. It installed without errors this time. REX4 seems to work with Windows 10 but have not verified completely. Thanks again
The install starts without issue but later stops with the following error "File b2su3.bmp_96 cannot install. Cannot be found in cabinet file rexte3.cab. I am running FSX on a computer on Windows 10. I appreciate your help.
