--- Comment #4 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

looks like a variation of bug 21790
The file 'portableRDP6.exe' is an executable created by AutoIt3/Aut2Exe.
It unwraps some MUI resource dlls, mstsc.exe and starts the main executable
'mstsc.exe'.

'mstsc.exe' itself is sandboxed/wrapped with 'MoleBox', an application
virtualization and software protection scheme similar to Thinstall and
Xenocode.
It ships and maps the native 'mstscax.dll' component as in-memory resource.

Relevant part of trace log:

--- snip ---

The failure to create the activation context seems the problem here.
As quick test I faked success in debugger and the client successfully displayed
the RDP login dialog.
