terminal output

The installer starts and gets past the initial file extraction stage, then I'm
getting an error message titled 'Unhandled Exception'. The contents of the
error message:
'Error number: 0x80040707
Description: Dll function call crashed:
ISRT._SetTitle
Setup will now terminate.'

Afterwards the installer quits.

According to my testing this was introduced by

commit e5edbc6fa00192a8048a3b81c70075537eaa2c97

ole32: Use proper IUnknown implementation when finding and creating stub
manager.

The commit can't be reverted cleanly on current git, but the installer works
properly with the previous commit 60451f9855791a6ee4d10ca569153df51249711b.
