How to Remove Ogacheckcontrol.dll Error

Ogacheckcontrol.dll is a module associated with Office Genuine Advantage or OGA. Office Genuine Advantage is similar to Windows Genuine Advantage as the former requires Microsoft Office users to validate their copy of the software to be able to obtain MS Office updates and downloads.  Since January 2007, MS Office users have had to validate their copies as legitimate. Copies of MS Office that fail the validation will still work, but the functionality is reduced drastically as users are only be able to view but not edit Office documents.

Sometimes, Office Genuine Advantage does not work even if the copy of Microsft Office is authentic.

Here is a fix you can try if Office Genuine Advantage’s ogacheckcontrol.dll is giving you problems.
