Salesforce for Outlook error 'The file adxregistrator.exe' is not marked for installation'

Important: Deprecation Notice

Salesforce for Outlook (SFO) is no longer available for new customers as of Winter '19. If you are looking for the current Salesforce email integration solution, see the Salesforce Help for details. 

Cause

Sometimes the uninstaller is unable to remove a reference to an older version of the Salesforce for Outlook (SFO) application in the Windows registry. This leftover registry entry may prevent a newer version of Salesforce for Outlook from being installed successfully, resulting in the error: "The file adxregistrator.exe is not marked for installation."

Решение

To resolve this issue you can perform the following steps:

 

STEP 1

  • Use the Microsoft Utility to uninstall Salesforce for Outlook completely and then manually install it, it should address this issue. Microsoft utility will remove any duplicate or extra keys from the registry that are causing the installation to fail.
  • If STEP 1 did not resolve the issue, try the STEP 2 OR 3 below



STEP 2

You can also ask your IT department to create a new Windows profile (username) on your computer and see if the that resolves the issue. Once everything is working in the new Windows profile then you can ask your IT to transfer your data. Your IT can simply log in with their account and rename your Windows profile from C:\users\ and have you re-login. Your old profile won't be deleted in case this does not resolve the issue.
For example: If your username is JDoe they can change it to JDoe.old

If you do not have an IT department, follow the steps below to create a new profile (Windows username). You can also refer to this link from Microsoft
1. You need to be logged in to your computer as a local Administrator to create this new account. You can do this from Control Panel | Users
2. Assuming you already uninstall Salesforce for Outlook, log off and log in with your new username.
3. Windows will take a little bit longer since it will try to configure your profile for the first time. Once you see your Desktop you try to install SFO and see if the issue is still reproducible before copying your data from the old profile.

Note: Always ensure that you must be logged off from your profile first, switching users will keep you logged in hence won't allow them to rename your profile

If you have an Exchange email, or company email, you must have your IT department assist you with this task. After you create a new user profile, you should create a new Outlook profile and transfer your Outlook data file along with My Documents, and other data.

Important References:
  • The Microsoft link below will assist you with creating a new Outlook profile if you do NOT have an IT department
  • Additional information from Microsoft support

If STEP 2 did not resolve the issue, try the STEP 3 below.
 

STEP 3

  • You can do a manual search for SFO GUIDs in the registry and delete them all and then try to install the new version. 
  • GUIDs are installed in the Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
  • Refer to article on Salesforce for Outlook Registry GUIDs for a list of SFO GUIDs
  • If you are not sure what version of SFO you or your users had previously installed, you may need to run a script or a batch file to search the registry for all of these GUIDs mentioned in the Article Salesforce for Outlook Registry GUIDs
