Microsoft have just rolled out a mass security update which will affect thousands of PC’s around the globe that are using Microsoft Excel which contain Addon’s and Macros.
The company I now work for are having this issue with their Accounts, and there are hundreds of affected PC’s… Which I have managed to find a fix for, and now have this running as a first run login script on all PC’s. To resolve this issue for yourself, use the following steps:
1. Close Excel.
2. Open a command prompt with elevated privileges (i.e. right-click cmd.exe and choose ‘Run as Administrator’).
3. Type the following at the prompt depending on which version of Windows you’re running:
a. For 32-bit Windows: regsvr32 "C:WindowsSystem32MSCOMCTL.OCX" b. For 64-bit Windows: regsvr32 "C:WindowsSysWOW64MSCOMCTL.OCX"
