File and Product Version From File info
Hi
I would Like to get the Product Name and version from the Exe File and use this information on the welcome screen.

I have tried MoreInfo plug in and can get it to work if run from with in a Section but if I place i call it from a function all the values are blank.

I want to just set the file name and location and it pick up the product name version etc automaticaly thus I would only need to change one line each time I need to build an installer!

Any idea why I can only use MoreInfo after the welcome screen in a section?

!addplugindir "."
!addincludedir "."

!include "nsDialogs.nsh"
!include "winmessages.nsh"
!include "logiclib.nsh"

; !include "MUI2.nsh"

OutFile "test.exe"

Function .onInit
        InitPluginsDir
        MoreInfo::GetFileDescription "$SYSDIR\rundll32.exe"
        Pop $0
        MoreInfo::GetFileVersion "$SYSDIR\rundll32.exe"
        Pop $1
        MessageBox MB_OK "[$0]$\r$\n[$1]"
FunctionEnd

OK It was / is working but only when I run it from inside HM NSIS!

I think the problem is that the file I want to use to get the information from is the the main file I'm delivering, so at the welcome screen it's still in the package!

can I use the moreinfo to get file info from the file to be delivered while still in the package so I can show the info on the welcome screen? Or is there a way of getting the info at compile time and saving it to be used during installation?

thanks

You should just be able to unpack the file to a temp location (like $PLUGINSDIR or $TEMP):

Function .onInit
        InitPluginsDir
        File "/oname=$PLUGINSDIR\somefile.dll" somefile.dll   
MoreInfo::GetFileDescription "$PLUGINSDIR\somefile.dll"
        Pop $0
        MoreInfo::GetFileVersion "$PLUGINSDIR\somefile.dll"
        Pop $1
        MessageBox MB_OK "[$0]$\r$\n[$1]"
FunctionEnd

If it's the file you are packing then you should be getting version information from it at compile time, not at run time.

thanks Stu I will look into this.

Currently I have got around this by extracting it to the plugin folder so it gets auto deleted again and then reading its values from there.
