1. Run vSphere client from a computer that has IE 10 or greater to verify that you can in fact access the Zerto vSphere Plugin. 2. Upgrade IE to 10 or greater on the machine running the vSphere client. 3. For new installations, make sure User Desktop Experience is installed on the ZVM machine (can be achieved through Server Manager -> Manage -> Add Roles and Features -> Features -> User Interface and Infrastructure -> Desktop Experience). Note: If upgrading IE, or installing the Desktop Experience, you must restart the vSphere client app for the changes to apply. In addition, clearing the IE cache and history, also helps resolve such issues.
