You Dont need “Falcon 4.0” installed you only need to be able to point the installer at a valid “Falcon4.exe” which is on the original Falcon 4.0 install disk in the “Program Folder” (Just that one File saved some where)
If it was a failed BMS install you may need to fix the registry. If you had it installed and the decided to move it you should have “Uninstalled” it correctly by running the installer again.
And then you would not be having a problem.
But how do I fix this I still can’t install it. I did delete everything in the registry but I still get the same error.
