SharePoint 2010 Products Configuration Wizard Error

Got error message "The exclusive inplace upgrader timer job failed." when running SharePoint 2010 Products Configuration Wizard.

Solution:

• Deactivate Use Access Control on all SharePoint server(s), then restart the server(s)
• Give Windows Domain Adminitrator rights to the user used by the service SharePoint 2010 Timer (SPTimerV4)
• Give maximum rights in SQL to this Windows user: user sould be db_owner of Sharepoint databases and should have all Server roles (maybe not perfect considering security but allows the Products Configuration Wizard to run properly)
