Hi,

I was able to duplicate the problem on my PC as well. I traced it down to an error being generated by Windows in my code in my Port Monitor (which receives the printer data), at the command where I create a User Process to display the User Interface to the user.

The Windows API command I use is: CreateProcessAsUser

When I do, the Windows System throws the following error:

ERROR_SYSTEM_NEEDS_REMEDIATION
Error Number: 15623 (0x3D07)
Error Description: An error in a system binary was detected. Try refreshing the PC to fix the problem.

Although this error sounds really scary, I honestly think the issue is something else. I have double-checked my line of code, and I cannot find anything wrong with it: specifically that section of code:

- has been part of PDF reDirect for 8 years now,
- worked for all versions of Windows since Windows 2000 up to Windows 8.1
- worked for 32 and 64 bit versions of Windows
- works for other Windows 8.1 (Metro style) Apps such as Internet Explorer
- works for Windows 8 Mail App (I assume you checked this already)

My thoughts is that this is a Microsoft low-level Windows 8.1/Mail App issue that needs to be fixed by Microsoft.

My next steps: I am currently on a business trip, and do not have access to my main PC to develop new code, but I will be back in a week. When I get back, I'll take a look and do testing to see if I can find a workaround for this issue, but I have very little hope that I will. I will provide an update on this forum if I find anything. I will also contact Microsoft to report the problem.

I think the reality is that I think that a Microsoft patch will come eventually that will address this problem.

Cheers!


P.S. I provided a lot of technical details to help anyone (Microsoft?) to get to root cause or if another programmer has the same problem.
