Protected file crashes on Windows XP, works on W7-8

Hello,

I'm new to Enigma Protector v3.150 and just had my first issue while trying to protect .NET application. I'm not posting here to ask a question, but rather to help others who may be seeing the same issue.

I'm protecting a new .NET app with most of the features available, but I'm not using Engima API. I'm also using Virtual Box and compressing files which helped me make a folder of 16 files into a single EXE. The protect file runs fine on Wndows 7 and Windows 8, but crashes on Windows XP SP3.

I was was going to email support, but I spent sometime troubleshooting the issue. I disabled features one by one, one at a time and trying the app each time to see if the crash will stop. I used to a be a QA so I know narrowing down the issue to a feature or an option will help dev speed up resolution. The best I was able to get was an app starting then stopping immediately - loading window flashes and disappear. Until I disabled all plugins.

The app stopped crashing on XP when all plugins (4 were enabled) were disabled, so I started enabling the ones I wanted (4) one by one. I found out that when both isdebuggerplugin.dll and isdebuggerpluginx.dll are both enabled the crash occurs, everytime.

There are some other DLLs on the list that will cause the crash, but the point is, if you have a protecting app crashing on XP and working on other Windows platforms, work on disabling plugins until you figure out which one is your problem. I can have other protecting in place, so I'm not worried about not being able to enable those exact plugins for my app.

Hope this helps.

Hi Lizzard,

Thanks you for the experience, the plugins are really the most often case of the crash.

Some plugin are compatible with one kind of applications, other - with other application. All plugins are almost never compatible with any file.

Our recommendation - do not use plugins at all! Or, use it only if you tested protected application on the different Windows versions. Btw, some other plugins may affect server versions of Windows too.
