Setup Addonmanager does not work

[billstill]

I attempted to run the Setup Addonmanager after switching to the original Fs9 with cd disk 4 start up.  The setup program says it can not locate flight simulator despite me pointing to the directory.  How do I correct this problem?

If Addon Manager setup asks your flight sim location, it means the needed registry key is missing, is pointing to the wrong folder, or there's no FS9.EXE inside the location that it points to.

I think the problem was the fs9.exe like you said.   It was pointing to ver 9.0 exe and needed 9.1.
