Problem installing ODS

[Shack]

OK, this is the error messsage I get when I try to launch F4Patch with the Desert Storm option selected. eFalcon executable is selected.
What am I doing wrong?

Failed to apply patch Operation Desert Storm Theater -- File mismatch. C:\MicroProse\Falcon4\campaign\save\strings.idx does not match C:\MICROPROSE\FALCON4\F4Patch\orig\strings.idx.orig or C:\MICROPROSE\FALCON4\F4Patch\desstorm\new\strings.idx.
