Possible Cause  | Possible Resolution  | 
There is a communication problem between the Hyper-V host and the Zerto Virtual Manager. (There must be communication from the Hyper-V host to the Zerto Virtual Manager.)  | Check communication from the virtual machine on which Hyper-V is running to the machine on which Zerto Virtual Manager is installed by sending a ping command from the Hyper-V machine to the Zerto Virtual Manager machine.  | 
The user under which Zerto Virtual Manager runs scripts on the Hyper-V host has insufficient permissions to create the folder \file on the host.  | Check if the user on the Hyper-V host has privileges to read and write on the local host file system. It could be a Run As Account user or the default, which is the Hyper-V host machine user.  | 
The Hyper-V PS module is not installed on the Hyper-V host.  | Install the Hyper-V PS module on the Hyper-V host.  | 
The version of PowerShell installed on the Hyper-V host is lower than 4.0. (Zerto requires version 4.0 or higher.)  | Check which version of Powershell is installed. If it is lower than 4.0, install version 4.0 or higher.  | 
There is a communication problem between the Hyper-V host and SCVMM.  | Check the Hyper-V host status and its communication status in SCVMM.  |
