What should I do to fix the ogacheckcontrol.dll error on my system?
Ogacheckcontrol.dll is part of the Office Windows update process, therefore, it gets downloaded automatically once your system runs the update. This main objective of OGA is to keep a tab on all the pirated versions of Microsoft Office software just like Windows Genuine Advantage (WGA) that keeps a tab on Windows Operating systems.
Once OGA is installed, the pirated copy of Office will diminish the functionality of the Office Software. You will be able to open a file, but editing and saving will be limited. This will not let you run the Office update either. Also, every time you try to open any module of Office it will return one of the above listed errors.
This is true for a pirated version of Office, but sometimes even after purchasing a genuine copy of Microsoft Office, the installed OGA marks the Office software as pirated and reduces the functionality. This happens when the Ogacheckcontrol.dll file gets corrupted and identifies the genuine version as pirated. OGA cannot be uninstalled directly from Windows using the Add or Remove Programs utility.
How to resolve ogacheckcontrol.dll error when you are using genuine Office software?
There are two ways to get rid of this problem:
- You Can install the OGA software again and re-validate Windows
- You can run the Genuine Online Diagnostics.
Method 1: Reinstall OGA
You can install OGA by downloading OGAControl.cab from the Office Update Website. You can download the file and save it on the desktop so that you can access it easily. After saving the file follow these steps:
- Double-click the OGAControl.cab. It has 2 files ?OgachcekControl.dll and OgaControl.inf.
- Extract the files to the desktop.
- Log into the system as Administrator.
- Click Start and then Click Run.
- Type %systemroot%/system32 and Press OK to open the system32 folder.

- Overwrite the OgaCheckControl.dll and OgaControl.inf.
- Close the System32 folder.

- Type regsvr32 OGACheckControl.dll and click OK.
- This will register the OGACheckControl.dll file and the message ?DllRegisterServer in OGACheckControl.dll succeeded.? will pop-up on the screen.
