I recently added some new HDD's to my WHS2011 server.
DrivePool was flawless here.
I went into Scanner to check that they had been detected OK, and all was looking good there too.
I went into settings, where I noticed it said v2.4.0.2929 in the bottom left corner.
Wondering if that was the latest I checked the website and found version 2.5.1.3062 available for download.
I do have Automatically Check for New Version selected.
I duly downloaded the file and went to install it.
It did not install, and the "error" simply said that the add-in was unable to be installed.
No more explanation than that.
I thought, no worries, I'll just uninstall and reinstall.
When I went to uninstall I see the version in the Add-ins tab says 2.5.3062.
I'm going to presume that I do have v2.5, that Check for New Version is working, and that the version reported in the settings box is wrong.
