MS Excel: C:\Windows\System32\SGXLADDIN.DLL

SGXLADDIN.DLL could not be found Error

ERROR: C:\Windows\System32\SGXLADDIN.DLL could not be found.


This error occurs when you launch Microsoft Excel 2007, 2003 or 2002 following the installation and subsequent uninstallation of a Sage product such as Sage Line 50 Accounts & Sage Instant Accounts.


When a number of Sage products are installed they also install a Microsoft Office Addin file called SGXLADDIN.DLL which provides integration between Microsoft Excel and the Sage product however when uninstalling certain Sage products the addin reference is left inside Excel but the file is removed, hence the error.


Luckily, this one is very simple to fix.  Read on.



Solution 1: Microsoft Office 2007 Users:

  1. Open Microsoft Excel
  2. Click the Microsoft Office button (that’s the large ugly button in the top left hand corner)
  3. Click Excel Options button at the bottom right of the menu
  4. Click Add-ins in the left hand navigator
  5. Now in the right hand pane, click the Manage Add-ins button at the bottom – the Add-ins dialog should appear.
  6. Clear the checkbox next to the add-in that reads SGXLADDIN.DLL
  7. Click OK and restart Excel


Solution 2: Microsoft Office 2003 & lower Users:

  1. Open Microsoft Excel
  2. Click Tools > Add-ins…
  3. Clear the checkbox next to the add-in that reads SGXLADDIN.DLL
  4. Click OK and restart Excel

    worked thanks. In 2010 you have to go into the options, select excell add-ins from the menu at the bottom, then un-select the sgxladdin. It will say “missing ok to delete?” and if you ok then restart the error is eliminated.
