Greetings
Seems that your Network service doesn't have enough permission on the root of the drive you’re installing vCenter on.
i will explain you now step by step how to bypass this error and solve it :
- Right-click the root drive and click Properties .
- Click the Security tab.
- Under "Group and user names", click Add.
- Enter Network Service then click ok.
- Check Allow for the Read permission for the Network Service account in the Permissions for Administrators pane.
- Apply and here you go .
Let me know if you still have problem .
