Error installing Sophos for Virtual Environment on Hyper-V Host: Security VM: Failed to set Mount Point for Config VHD

Hi Everyone,

This is my first time on the forum. Hope you have some ideas on this issue. I have just tried to install the Sophos Security for VM on a Hyper-V host and I have received an error. An extract of the log shows the following:
