Hello @mikaelmello, welcome to the forum!
It’s possible the issue you’re getting with “could not get resource” error is related to the location of your webroot folder (usually inside the Duplicati 2 program folder for installs or /bin/Release for Visual Studio builds).
I would suggest you try downloading the latest version again as 2.0.0.7 is VERY old (2.0.3.11 was just released) so you may just be running into an issue with that old version.
