WinRAR Software

[Felix_Nietzsche]

I'm trying to apply a patch to update some software and it requires WinRAR software. The problem is the WinRAR software opens the zip file just fine. Then I run the patch, things seem cool, but the software NEVER gets updated.....

Could this be because I have not bought a WinRAR license? If this was the case, I would expect to get a message saying I need buy a license but it says nothing. Any sugestions what I need to do to apply this patches? Based on the lack of messages, I'm not sure if buying a license will solve my problem...
