Description: During installation of CA ARCserve Backup Agent for Virtual Machines, the following may appear in few instances:
'Setup was unable to update the VDDK driver. The agent, and any previously installed release of the agent, was uninstalled from your computer. To correct this problem, uninstall VDDK from your computer and then reinstall the agent'
Solution: This issue occurs only when Setup cannot uninstall the VDDK driver that is installed on the agent node. As a result, Setup uninstalls the current release of the agent and, if a previous release of the agent was installed on the node, Setup uninstalls the previous release of the agent from the node.
To fix this issue, you need to uninstall VMware VDDK from the node manually and then reinstall the agent. You can uninstall the VDDK using one of the following methods:
From Windows Add or Remove Programs:
Uninstall the application that installed VDDK or
From Start > Run> cmd to open the command line. Execute the following command:
sc delete vstor2-mntapi10-shared
After the command completes, restart the computer.
Please try installing the agent after the machine reboots.
