If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. See the article to backup the registry on your machine or ask one of your IT team members to perform the following tasks


1- Close all programs, specially the Microsoft Outlook and Salesforce for Outlook (SFO)

To close SFO, right click on the SFO system tray icon and click on EXIT,

2- In Windows Vista/ Windows 7 / 8 / 8.1 /10 you need to make sure the UAC (User Account Control) is set to Never Notify. Review our documentation on how to change the UAC setting

3- After you adjust your UAC using the article mentioned in Step #2 above and restarted your PC, open up Windows Registry Editor by typing in Regedit in the Run Command box. To open the Run command box, press and hold down the Windows key on your keyboard and press the key to pop open the Run command box and type in the following and press Enter

9.2       for       Office 2003
9.3       for       Office 2007
9.4       for       Office 2010
9.5       for       Office 2013
9.6       for       Office 2016


For example, if you have Office 2013 then you should only have the 9.5 key. Or in a different scenario if you had Outlook 2007 on your machine first then installed Outlook (or Office) 2010 on top of Office 2007 you may end up with 2 keys in this location.
