Seamless RDP with RemoteApp Tool and freerdp

Operating Systems & Open Source

Usually with RDP you access the entire desktop including all running applications in a single window, but there is also a way to access individual applications with individual windows so that the experience becomes more seamless, but I was not able to get it to work. I followed wendell’s guide, but got stuck on an error message.

The problem specifically appears to be with the /app flag of xfreerdp because without that flag it works just fine for me:

xfreerdp3 /cert:ignore /u:user /p:user /v:192.168.3.50:3389

(As you can see, the entire desktop is shared. It’s not the seamless mode I’m looking for.)

But when I use the /app flag to only access a single application it doesn’t work:

xfreerdp3 /cert:ignore /u:user /p:user /app:'%windir%\explorer.exe' /v:192.168.3.50:3389

I get this error:

[21:52:26:671] [22579:00005833] [ERROR][com.freerdp.client.common.cmdline] - [freerdp_client_settings_parse_command_line_arguments_int]: Command line parsing failed at 'app' value '%windir%\explorer.exe' [-1002]

Using wlfreerdp3 I got the same error, as well as a deprecation warning.

This is how I allowed access to Windows Explorer via RDP on the Windows-side using RemoteApp Tool:

Any ideas why I’m running into this error?

Host: Manjaro Linux with Wayland, Gnome 46 and FreeRDP 3.7.0
Remote: Windows 10 with RemoteApp Tool 6.1.0.0.

Hi, perhaps, maybe try /app:program:'%windir%\system32\explorer.exe'

Thank you, with /app:program:'%windir%\explorer.exe' it is finally working now. :slight_smile:

thanks to the dev who squashed thousands of bugs in the app.

seems odd, and not clear in documentation

I added a Wiki page for this on the RemoteApp Tool Github now:
