Modern app crashes Error code: 0x80040150

Question

Hi *

I have an app published in the App Store (Windows 8 / 8.1). I took the crash reports available in the developer's portal and tried to understand where is crashes by using Windows Debugger. When I check the managed stack (my app is in C#) I see that my app crashes in the Main method. And if I see the error message .. this is what I see:

Error code: (HRESULT) 0x80040150 (2147746128) - Could not read key from registry

I know that my app runs fine in a lot of computers. And based on the description of the error. It doesn't look like it's a problem in my app because I understand that Modern apps don't have access to Registry. 

Any idea what is the cause of this error in the context of modern app?

Answer 1

Can you share the dump file via OneDrive? What does the managed callstack look like in Windbg? You can use the "!clrstack" command in Windbg to print the managed callstack.

I have to check if I can share the crash dump. First . But I ran the command you suggested (plus others) and this is what I see. Anything else that I can explore?

The user dump currently examined is a minidump. Consequently, only a subset
of sos.dll functionality will be available. If needed, attaching to the live
process or debugging a full dump will allow access to sos.dll's full feature
set.
To create a full user dump use the command: .dump /ma <filename>

Did you ever get this figured out? The dump file is not a full dump, so unfortunately the managed stack won't be able to show you anything as such, what does the native callstack look like? Use the "k" command.
