Attached zipped patch file that seems to fix the issue.

The only change in the patch is to comment out the next line in WindowsPlatformIntegration.cpp m_propertiesRegistration.setValue(QLatin1String("shell/open/ddeexec/."), {});

Edit: I had to delete the bad registry entry during testing. `[HKEY_CLASSES_ROOT\OtterBrowser\shell\open\ddeexec]

@="@Invalid()" `
