Question

My question is if there is an alternative plugin similar to LogicLib? One that does support numbers like 17.0.8.22 since my program version that’s in the registry is a number like that and it seems like LogicLib does not support this for Windows 7.
It does recgonize it like this:

${If} $0 = '17.0.22.0'

But this is failing/being ignored,

${If} $0 > '17.0.22.0'

As Anders states, the VersionCompare macro can handle complex version comparison.

Here is a little example:

!include "logiclib.nsh"
!include "wordfunc.nsh"
OutFile "version.exe"

!define v1 "1.4.0"
!define v2 "1.3"

Section

    ${VersionCompare} "${v1}" "${v2}" $0
    ${select} $0
        ${case} 0
            messagebox MB_OK "${v1} = ${v2}"
        ${case} 1
            messagebox MB_OK "${v1} newer than ${v2}"
        ${case} 2
            messagebox MB_OK "${v1} older than ${v2}"
    ${endselect}
