Great work and thanx for sharing.
I've the server running on IIS (Windows 2008 R2) but I connect only with HTML4 (not 5) and only to the server itself (localhost).
Nothing meaningful enabling debug mode, in log file

Hi Red,

Does the rdp client process start and stop at the same moment (with like a millisec span)? If so, it's an issue with FreeRDP (the rdp client). It has nothing to do with the rendering mode (HTML4 or 5).

Do you have installed the Microsoft C++ 2015 (x86) reditributables? You can check that into the Windows "Programs and Features". Notice the "x86" thing, because FreeRDP is built in 32 bits (it has some 32 bits dependencies, OpenSSL being one of them).

Please keep me updated. You can also open an issue on the (issue tracker, it will ease following the problem.

You can also try to run "FreeRDP.wfreerdp.exe", located into the Myrtille "bin" folder; if there is a missing dll dependency, Windows should display a message box indicating which one is missing.

Thanks again,

Hi Red,

Thanks for the issue screenshot. The problem is that your RDP server has NLA authentication enabled. As I state into the documentation, there is an issue around that (due to FreeRDP being an old version (0.8.2) or OpenSSL certificate check, I don't know exactly...). I ended disabling NLA (anyway, the browser isn't able to transport it).

Please try to set "standard RDP authentication only" on your RDP server configuration.
