Comment 1 Andrew Nguyen 2009-12-22 01:59:32 UTC 
I'm confirming with wine-1.1.35-56-g13a9c03. Some cursory tracing makes me suspect that the application depends on various Terminal Services components for its operation. The application installer can be downloaded from (http://tsplus.net/PortableRDP6.exe).
Comment 2 Andrew Nguyen 2009-12-22 02:02:29 UTC 
Interestingly, I notice that copying mstscax.dll from the redist available at http://www.microsoft.com/downloads/details.aspx?familyid=72158B4E-B527-45E4-AF24-D02938A95683&displaylang=en into the program directory allows mstsc.exe to spawn. It seems the essence of the program is to spawn some copy of mstsc.exe.

Comment 4 Anastasius Focht 2013-12-26 11:36:51 UTC 
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.

Comment 5 Anastasius Focht 2013-12-26 12:53:55 UTC 
Hello again,

actually it's expected that CreateActCtxW()/RtlCreateActivationContext() fails at this place due to invalid 'lpSource' argument (file/path only exists as mapping in memory).
The problem is what Wine returns as last error.
