Correcting VISTA problem
OK, I have some new information that might help with these Vista problems.

I think the problem is with something in Vista called DEP (Data Execution Prevention). It appears that DEP is being enabled by default on new Vista machines, and it might be getting turned on by a new Vista patch.

To see if DEP is enabled on your Vista system:

1) Press Win+R to open the Run dialog box.
2) Type "SystemPropertiesDataExecutionPrevention" (without the quotes) and press Enter.
3) Click Continue, if prompted by User Account Control.
4) Under Performance, click Settings.
5) In the Performance Options dialog box, click the Data Execution Prevention tab. If your processor supports this feature, a sentence to that effect appears in the lower part of the dialog box.

You can turn off DEP for user applications by selecting the option "Turn on DEP for essential Windows programs and services only". Then click OK and close all of the dialog windows. Then you MUST REBOOT for this change to take effect.

After turning off DEP and rebooting, then try running CMUD to see if it works.

If CMUD works and you don't want to leave DEP turned off, you can go back into the DEP dialog and select the option: "Turn on DEP for all programs and services except those I select" and then click the Add button and add the CMUD.EXE program to the list of exceptions (and make sure there the checkbox next to CMUD.EXE gets checked). You'll again need to click OK and again need to Reboot to save the changes.

Please let me know if this helps. The new version of Armadillo seems to be full of bugs, so I am *not* going to upgrade the Armadillo in the 2.0 version of CMUD. I need to wait until they fix their bugs before I'll change the copy protection. But this DEP issue seems to be causing the same crash in other Armadillo applications, and it only happens on Vista systems with DEP enabled, which is currently the minority, but it slowly increasing.

Btw, apparently the latest update to Windows Server 2003 also enables DEP, so this same problem might be occuring on non-Vista systems with DEP enabled.

Zugg, it seems making topics sticky takes a bit more access then I have. So when you get a chance please sticky the topic.

Also you might want to replicate this in the zMud forum so it is posted with your name. I was thinking about using a move with shadow, but I don't know if the shadow topic can be stickied.
The only good questions are the ones we have never answered before.

I've stickied this topic. I don't want to post this to the zMUD forum, because I don't want to give the false impression that zMUD is supported on Vista. While this DEP stuff helps, there are still several issues with zMUD and Vista that will not be resolved.
