There is still no newer release. Is current beta installer 2.8.6.3 ok for production?

Hello Madshi! On Windows 7 Pro X64 your MCH driver sometimes causes a 0x50 Bluescreen. It is signed with my EV cert (with cross signing) and signed by MS. If I omit MS signing, those crashes do no occurr. On Windows 10 there are no bluescreens with that binary. It is tested with MCH installer 2.8.6....

Hi Madshi!
Is there a solution for my problem in near future?

Yes, the 32-bit sender is the problem.

No, I do not have access to the source code. I use v4 linking the static lib files into my executable.

Yes then it works, but the "reply" is the important thing in my case

ist is \RPC Control\mchIpcTEST. If the queue is not available, my SendIpcMessage test executable immediately fails and there is no timeout. just as expected.

sorry I ment the queue process. the sending process is system account of course.

I tested all three failed combinations with elevated sender: nothing changed

Hi Madshi! I want to send IpcMessages from my system process running in session 0 to my user process running in an input session. It does function, if I use 64-bit processes on 64-bit platform. If I run my 32-bit compilation on a Windows 7 32-bit machine, all IPC calls run into a timeout of approx. ...

Hi Madshi! When a "global file mapping" is created within a console session (e.g. 1), my system process within session 0 cannot open that mapping. Last error equals 2. The same file mapping can be opened from within the console session by other processes. "Global file mappings" c...

Hello! I have a problem in Windows 10 x64 1703 (and newer insider builds). In Edge my hookdll (DLLmain) cannot send an MCH IPC message to its service. The IPC-queue has no special security descriptor and can be accessed all other (normal) processes. But in Edge the message is not sent and lastError ...

OK thanks
