hello Admin

//设置应用程序处理异常方式：ThreadException处理
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
//处理UI线程异常
Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
//处理非UI线程异常
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);

the windows event log records seems that , clr crash code is 0xc0000409

Hello Admin,

I was receive the latest build 3.5.0.1265 , but the problem still exist.

because of my .net app is a large program , i can not get the exact Fault location .

could you give me some reason which could cause clr crash as error code 0xc0000409?

or how to trace stack in protected mode.

Oh,i build example and send it to info@vmpsoft.com <info@vmpsoft.com>; >_< forum attachments cause error that i count not upload it

run it ,wait half an hour, crash

We have checked your example and it works fine.

my example is not an immediate crash. could you give me you clr.dll version? my clr.dll version is 4.8.4341.0

i can not confirm the problem is a .net rumtime bug , or is vmprotect bug.

i test my .net app on 3 computers , both windows 10 , the error same . clr.dll version is 4.8.4300.0 \ 4.8.4341.0

Dear Admin,

I have the same problem which is on going via this thread. here is the detail.

I have VMProtect Professional version 3.5.0. I have protected my two dotnet desktop application. one is developed using WPF and another I have developed using Window C#. In both of this application if system is either idle for a long duration e.g 10 mins sometime or sometime 2 mins also And in another WPF system if my printing is going on then in between of that , I am getting below error in event log of window 10/ 7 operating system.
Error Detail:-

Report Id: e2c2b22d-e62c-11eb-8853-1c1b0d312693

Issue is there so might be I can not share my full project and even it’s uncertain problem not sure always come but suddenly system stop working and from my both the project , I am getting the above log.

Without protection , it’s working perfectly.

Only Memory protection is On , rest all the options are off.

Thanks,
Parita
