NSIS Get Product Version

Question

I am trying to get the ProductVersion using NSIS 2.49. Does anyone have examples on how to get the product version?

GetDllVersion  \"C:\\data\\Some.exe\" $R0

NSIS does not have native support for this, you have to call the Windows API directly:

Function GetDllProductVersion
System::Store S
Pop $3
System::Call 'VERSION::GetFileVersionInfoSize(tr3,*i)i.r4'
System::Call '*(&i$4,t""r1,t""r2)i.r5' ; Set $1 and $2 to "" so they are empty if we fail
StrCmp $4 0 fail
StrCmp $5 0 fail
    System::Call 'VERSION::GetFileVersionInfo(tr3,i,ir4,ir5)i.r0'
    StrCmp $0 0 fail
    System::Call 'VERSION::VerQueryValue(ir5,t"\",*i.r6,*i.r7)i.r0'
    StrCmp $0 0 fail
    System::Call '*$6(i,i,i,i,i.r2,i.r1)'
fail:
System::Free $5
Push $1
Push $2
System::Store L
FunctionEnd
