Hi everyone. I’m new with Duplicati and really like as far as I’ve used it. Now I’m trying to install it on Hyper-V Server 2102R2 (core server) and I’m having problems with VSS. It installs and works OK but I cannot use VSS for backuping my VMs because of AlphaVSS.x64.dll dependencies. The problem …

I ran into a similar issue with one of my fresh 2012R2 servers (for another project). You need to manually install the Microsoft service pack SP1 for the OS (it does not come in via Windows Update), then the C++ redist should install, and should be able to continue on.

Did you try verifying whether or not the files exist as described here?

Also, can you provide the actual Duplicati and / or C++ redist. install errors that you are seeing?
