Much more sensible would be a situation where developers are people who at least understand how these things work, what they "develop". Reading your story, all my body hairs got up. Great that you said who the developer is, now I'm going to try not to use this program anymore. Or at least I'll try to use as less as possible.
As this not the only thread about Winrar... Can someone explain to be, what Winrar can do, that 7zip cannot?
It can create rar files Not commenting on the nonsense in the OP. The keygen nuking info he already got in a convo.
WinRAR can run just fine even without a license. I don't see what the big deal is. (but then again, I don't use WinRAR as often, even though I had it on my system for over eight years)
I gave him a working rarreg.key a few weeks back (in an effort to shut him up), in a convo where he got served the exploit he seems to have given to someone at rarlabs (doubtful), got no normal response, only nonsense, so we left the convo.
They haven't changed the licensing since the beginning so there was no point in creating a keygen anyways.
7zip is nearly equal to winrar and free but most geeks use cracked winrar than 7zip including me. The reason for using winrar by most because it is popular in warez forums from long time when people didn't know 7zip. LHA, ARC, ARJ and Pak (very old command line archiver) also are good but people always stick to winrar.
I also did Vietnamese translation for WinRAR while ago, rarlab was very nice giving me a lifetime free license as well I like them and their software.
