It's a known issue.

To bypass it, enter the tutorial mode and then start the main campaign from there.

Yes I have said this in the original post. I am actually looking for a way to bypass this.

There's also zeus's patch:

Yes, I managed to find it the last night. The patch works on one of the versions, but 2 of the others I tested crash with it. Maybe that's because of version differences (there was even text difference in them). I noticed the patched exe has NOP in it so DxWnd could find what needs to be done.

Why would you be using three different versions of the game? Which versions don't work exactly? Why do you want to play them?

I own one, and that only doesn't work. So I searched online what's downloadable and the patch works there...

OK, some details about the one you own might explain why it doesn't work, which release is it? What version is Heretic II? Does the official 1.06 patch work?

The game works on my Win XP without issues. It is released with 1.0 only. So I install the 1.06 patch and it's the same. The quake2.dll are of different sizes, in the 1.06 patch, working ones have same size while the OWNed one has a larger size. If I recall correctly, the 1.1 patch also had size diff in quake2.dll

Again, which release do you own?

It doesn't say anything about a release. The one that doesn't work has a Raven Software logo on front on the right corner. The one that did work, their download page has a cover with the ESRB T logo on bottom right. And the Raven logo in on left above Activision logo.

Though while it might be interesting to see why it doesn't work on whatever release you do have, does it really matter? Unless there's something significantly different about it, just download a copy that works. I don't really see the problem.

That's true but I really wanted to put the CD in use, at least for some days before I save it in storage as antique...

Edit: Just checked both the CDs now together, the Autorun is different as well, one has Heavy Gear II styled, and the other has a 16-bit Autorun. The quake2.dll has a difference of 1 year in file size, and many files such as WinSnd.dll don't exist in the working one.

I recently acquired a new older version of heretic II myself and I can say there are different versions of the game and I have had issues with various versions interacting differently with patches. I also recently got the game to run almost flawlessly too. I am using nGlide and 1,06 patch.

However, I forgot to add, so far i cannot load saves I make within a level i can only load autosaves that start an area. I am worried this will be an issue once you start backtracking into areas.
