64bit error

The above error only shows when when compiled as 64Bit.
When debugging and in 32bit, all works fine.

Is there a log written somewhere that can point me in the right direction on where to look for the problem?

Edit: The App launches multiple concurrent async shells and http requests and then processes the results. It happens randomly every 10 requests or so. Since I cannot debug, I don’t know if it’s from a (classic framework) shell, a (new framework) httpsocket call or something completely different.

add code to app.UnhandledException event to show message box with stack trace of the exception.

Nice!
Thank you
