compare file version
I want to compare two files versions numbers - in order to know whether to replace a certain dll or leave the current one.

Using the macro GetFileVersion i receive the two versions' numbers from both files.

Now i need to actuallt compare the two numbers.
I am looking for another macro or something else that will be able to compare it correctly. I can not find. I always can parse the two numbers and compare it myself - but ...

does anyone know how to do that?

Use VersionCompare in NSIS\include\WordFunc.nsh.

it doesn't really works OK
for instance:

Comparing 0.9.81.70 with 0.9.8.7
returns 0 - meaning equal.

Am i right?

If it's the same code as that of two years ago (which at first glance appears to be just the case), then yeah it doesn't do >9 sub-version numbers. Feel free to edit the macro and share. :-)

Well - I'm new to NSIS so i wouldn't know what was two years ago ;-)

for the same reason I still don't know how to right a macro and how to publish it later.

I will try to do that

What version of NSIS are you using?
I just tested your version numbers and several others, and the result is as expected.

My version of the Word Functions Header is v3.3.

that's weird. I'm using the same Word function header
My NSIS version is 2.4

How could that happen?
