Can the setup filename be derived from the executable file version number?

Question

Is it possible to get Inno Setup to read the file version of the main executable file and set the name of the created setup to something like "myapp_setup_1_0_3708_19805.exe"?

Answer 1

You should be able to 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.
