Failed to open VMDK. ESXi 5.5 and Veeam 7.0.0.764+
Challenge
After updating Veeam or VMware such that a combination of ESXi 5.5 and Veeam 7.0.0.764 or higher exist within the environment, the jobs fail with error “Failed to open VMDK” and/or “Host not licensed for this feature.” The job will successfully download the VMX, VMXF, and NVRAM, but will fail on the VMDK.
In Veeam Backup & Replication v8 this issue appears with the error “Failed to create processing task for VM <vmname> Error: Cannot access VMX file of VM ‘<vmname>’” and “Task failed Error: Cannot access VMX file of VM ‘<vmname>’”
In Veeam Backup & Replication v8 this issue appears with the error “Failed to create processing task for VM <vmname> Error: Cannot access VMX file of VM ‘<vmname>’” and “Task failed Error: Cannot access VMX file of VM ‘<vmname>’”
Cause
This has to do with a change in how VDDK was utilized after 7.0.0.764 within Veeam when interacting with ESXi 5.5.

More information
If the “Add Permissions” option is greyed out when you attempt to add the account as an Administrator at the VC level please use a different account. (The local Administrator account of the VC will most likely work best.)
