MyAppVersion - Reading first two parts of a version number

[Ertan Küçükoglu]

Hello,

Normally we can manually put in the version number 

#define MyAppVersion "35.832"

or read it from an EXE file 

#define MyAppVersion GetVersionNumbersString('MyApp.exe')

What I would like is to read just first two numbers out of four from a version string. For example

"9.3.0.147" should become "9.3"

"15.280.0.12345" should became "15.280"

Is it something that can be automized to be read out of exe with combination of some other functions? Or I need to write it manually in my ISS file?

Thanks & Regards,

Ertan

Use GetVersionComponents instead.

I am pretty sure it is easier than what I am trying to do (which fails anyway)

I could not handle this myself. I tried the code below as my last try and this also seems not to work.

#define Major

#define Minor

#define Rev

#define Build

#define AppVerText GetVersionComponents('..\Win32\Release\MyApp.exe.exe', Major, Minor, Rev, Build), Str(Major) + "." + Str(Minor)

[Setup]

AppVersion={#AppVerText}

I do appreciate any help.

Thanks & Regards,

Ertan

It might be your relative path that's not working, try with an absolute path?

After posing I figured that my EXE does not have a product version. It has FileVersion only.

I switch using ParseVersion() as below which is working just fine

#define Major

#define Minor

#define Rev

#define Build

#define MyAppVersion ParseVersion('..\Win32\Release\MyApp.exe', Major, Minor, Rev, Build), Str(Major) + "." + Str(Minor)

                                             

[Setup]                       

AppVersion={#MyAppVersion}

Thanks & Regards,

The definition of MyAppVersion is not correct... Can you try the following?

#define Major

#define Minor

#define Rev

#define Build

# define FullVersionString GetVersionComponents('..\Win32\Release\MyApp.exe', Major, Minor, Rev, Build)
#define MyAppVersion Str(Major) + "." + Str(Minor)

Is it valid also Inno Setup 5.x?
Because it seems that " GetVersionComponents" is only for Inno Setup 6.x.
How can do that with inno Setup 5.x and get only 3 parts (x.x.x) of version?

GetVersionComponents was added in 6.x.  If you can't upgrade, you'll either have to use ParseVersion from ISPP or GetVersionNumbers at runtime.
