Get Application Version

[Dan Bomsta]

I have used Inno Setup many years ago and the following worked well

#define MyAppVersion GetStringFileInfo( "AddBackslash(SourcePath) + \someApp.exe", "ProductVersion" )

Now using version 6.7.1 GetStringFileInfo and GetVersionNumbersAsString to do work.  So I added a function, which successfully retrieves the version info.

/////////////////////////////////////////////////////////////////////
function GetVersion(Param: String): String;
  var
    Version: String;
    Filename : String;
begin
    Result := '0.0.0.0';
   
    Filename := ExpandConstant('{app}\someApp.exe');
    Log('ExapandConstant returned: ' + Filename );
    if (GetVersionNumbersString(ExpandConstant('{app}\someApp.exe'), Version) ) then
      begin
        Log('Version info: ' + Result);
        Result := Version;
      end;
end;

Then I figured in [Setup] I could use the GetVersion function with OutputBaseFilename={#SetupBaseName}{code:GetVersion}.  The compiler does not like this though it works in the sample script CodeExample1.iss

I am unsure what else to try.  Any advice is appreciated.

The first quote is in the wrong place, so I do not think this can have ever worked. There is also an extra, unneeded backslash.

This works for me:

#define MyAppVersion GetStringFileInfo(AddBackslash(SourcePath) + "someApp.exe", "ProductVersion")

Which can be written shorter as:

#define MyAppVersion GetFileProductVersion(AddBackslash(SourcePath) + "someApp.exe")

Then I figured in [Setup] I could use the GetVersion function with OutputBaseFilename={#SetupBaseName}{code:GetVersion}.

Using {code:} does not work here because it is runtime functionality, not compile time.

Greetings,

Hi Martijn,

Thank you for the quick reply.  I have tried both defines you shared; neither are working for me.

[jeff weir]

FWIW, I use this to get the string you are looking for:

#define verinfo_file_version GetVersionNumbersString("{full_path_to_exe}")

[Martijn Laan]

This means the file does not exist, or does not have a product version in its version info. 

Greetings,

Martijn

Hi,

That doesn't get the product version though.

Greetings,

Right! 

How about this - assuming the version info is 'correct':

#define verinfo_file_version GetVersionNumbersString(verinfo_source)
#define verinfo_product_name GetStringFileInfo(verinfo_source, PRODUCT_NAME)

#define verinfo_product_version GetFileProductVersion(verinfo_source)

AppName={#verinfo_product_name}

AppVerName={#verinfo_product_name} {#verinfo_product_version}

AppVersion={#verinfo_file_version}

OutputBaseFilename={#output_filename_prefix}_{#verinfo_file_version}

I can confirm all those work on 6.7.1 ;-)

Jeff's second solution works, I didn't try the first.  I defined verinfo_source as the full path string to the exe.

It is unclear why the usual way #define MyAppVersion GetFileProductVersion(AddBackslash(SourcePath) + "someApp.exe") is not working.  At least I have a working solution now.

[Dan Bomsta]

Sorry...Thank you all for your assistance!

Oops, I forgot to include that part! I'm happy it worked out for you.

Was your exe actually in the same folder as the main .iss script?  That's what SourcePath means in ISPP; it has no relationship to the SourceDir [Setup] setting.

GetFileProductVersion gets the textual product version of your file. Jeff is using GetVersionNumbersString, which instead gets the binary file version of your file as text.

If the former is working but the latter is not, it just means your file has no textual product version set.

Note that there is also GetFileVersionString, which gets a third version, the textual file version. In case you are not aware, the textual and binary file versions are two truly distinct fields in a file's version info.

To make matters worse, there is a fourth version in a file's version info, the binary product version, again a truly distinct field. However, I do not think there is a function to get this value.

[Bomsta, Dan]

Thank you again to all of your for the information.

I can go back to using #define MyAppVersion GetStringFileInfo( AddBackSlash( SourcePath ) + "LabWingman.exe", "ProductVersion" ) by based on Gavin's response.  The Inno script and the executable were in different directories.  Placing the Inno script in the same directory allows one to use the aforementioned define.  Well, it has been a decade or so since I last used Inno Setup...the things we forget ;-)
