    You should be able to do it like this:

    (I haven’t tried this recently but it certainly worked back in 2007 when I was using InnoSetup in this way. It might need some slight changes if Inno’s syntax has changed since then.)

    #define MainBinaryName  "MyMainFile.exe"
#define SetupBaseName   "setup_mytool_"
#define AppVersion      GetFileVersion(AddBackslash(SourcePath) + MainBinaryName)
#define AVF1            Copy(AppVersion, 1, Pos(".", AppVersion) - 1) + "_" + Copy(AppVersion, Pos(".", AppVersion) + 1)
#define AVF2            Copy(AVF1,       1, Pos(".", AVF1      ) - 1) + "_" + Copy(AVF1      , Pos(".", AVF1      ) + 1)
#define AppVersionFile  Copy(AVF2,       1, Pos(".", AVF2      ) - 1) + "_" + Copy(AVF2      , Pos(".", AVF2      ) + 1)

[Setup]
OutputBaseFilename={#SetupBaseName + AppVersionFile}

    If MyMainFile.exe was version 1.2.3.4 then that should call the finished installer setup_mytool_1_2_3_4.exe

    The AVF1, AVF2, etc. stuff is just there to replace the dots (.) in the version number with underscores (_) to avoid causing problems with things that can’t cope with lots of dots in a filename.
