I’ve had issues getting the Nextcloud client upo and running on Windows machines (another reason to avoid them). Might it just be a case of needing to download/install the missing DLL? Maybe the windows update will address this.
Unfortunately that doesn’t seemed to have worked based on the Github issue thread, but installing the Windows Visual C++ redistributable seemed to have worked … along with a lot of restarts.
I just had another go at removing and reinstalling Nextcloud and it seems to have worked. I installed 3.9.1 & last time it was 3.9.0.
Thanks all for your help. Most reassuring.
