There is a new release 2.6.0, just published on Friday:

Could you give it a try and get back here with the results? ;-)

[ericohao]

Thank you every much.I tested.But , still the same. Thanks a lot .

[delumerlino]

Same here. Follow discussion

Subscribe for 2.6.0 when using Remote Desktop, than error occurs. When using e.g. Teamviewer, Client starts normally.

Same error on fresh-ish windows 10 install (1809, 1909) using remote desktop. Nextcloud client version 2.6.2.

Now I think about it this probably is not a new problem? Or at least something else also had similar problem before and the solution is to disable the app's gpu acceleration. But I don't remember how to do that.

Apparently it's common problem on systems running certain radeon driver? Renaming certain dll file seems to fix it.

Filename is: atig6pxx.dll

It's located in Windows directory.

Same issue:
2.6.2stable-Win64 (build 20191224) running on Windows 10 1909, if i open nextcloud via Microsoft RDP i get "Error: LoadLibrary failed with error 87:The parameter is incorrect.". if i'm running on desktop i can run it and than without close the session i can use the rdp.
Looks like a rdp compatibility bug

Same here. Client works when started from local session, then you can even connect via RDP and it's ok. Startet from an RDP it crashes.

[Plattenthaler]

Same here. Exact the same as Volker-K described.

Same issue for me. I work from home and need RDP connection over VPN to my work computer. From time to time I need to reboot it. When I login over RDP the Nextcloud client will not start with that exact name. If I reboot and login from behind computer the client will start. Any solution for this?

On Windows 10: If running this app over a remote desktop and you have an AMD/ATI card, simply disable the real graphics card in Device Manager and restart the application (not the computer). https://github.com/alacritty/alacritty/issues/1976

That's one way.
I've tried setting
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services]
"bEnumerateHWBeforeSW"=dword:00000001

It worked.

[ericohao]

Thanks. I think it is a problem of QT , several other application with QT in remote desktop session report the same message and cannot load , for example OpenSCAD. @Volker-K

[Volker-K]

@ericohao It's a problem of QT caused by a misspelled dll-name insinde the registry. So lots of Nividia drivers for AMD/ATI systems will cause this error. QT tries something that should normally work and obviously does with other graphics cards.

Here seems to be the relevant QT bug: https://bugreports.qt.io/browse/QTBUG-50371?focusedCommentId=329417&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel

I found a workaround by placing opengl32.dll from the MESA windows builds (https://github.com/pal1000/mesa-dist-win/releases/) in the Nextcloud installation directory.
