Updated:

* Fixed compiler flags to work on XP again, sorry about that.

Also you could change MajorLinkerVersion to 0E, MajorOperatingSystemVersion to 5, MinorOperatingSystemVersion to 01, MajorSubsystemversion to 5 and MinorSubsystemversion to 1 inside optional header to make it run on xp.. Although this solution is not really needed.. it's another way :)

To me its preferred if its done upstream, like its supposed to be. It was meant to be fixed, as it was a bug after all.

Setting:

[a] peHeader.MajorOperatingSystemVersion = 5;
[b] peHeader.MinorOperatingSystemVersion = 1;
[c] peHeader.MajorSubsystemVersion = 5;
[d] peHeader.MinorSubsystemVersion = 1;

would make a binary run under XP, although setting only [a] and [c] should suffice...
Having the source, however, mudlord's is the way to follow.

For those that care, released the source code to the current public and private versions of the packer.

What made you change your mind about releasing the source code? I thought that you said that it won't happen.

Somebody used it for bad things and it is now detected as virus by anti virus.. if you read the readme in the source you would not have to ask this question..

And since someone leaked it from Exetools, now bad people use it. So whats the point of fighting it? Might as well let the bad people have 100% control now. >_>

At least I still have mupack3 for myself, which has a completely different stub and different structure. It still uses the LZMA and rangecoder+lz77 decompressors since to me those are still decent. And it has better code preprocessing, and fixes the problems mupack2 had. And no, that won't be public to anyone.

So thank the bad people for ruining things. Seems people cannot be trusted.

Did a update a while back to get it to run on XP.

I wonder whats the point since XP is now deprecated, but nonetheless...

@mudlord
what about making "mupack" open source ?
