Unable to uninstall Elements Endpoint Protection from Windows / Mac, getting error: « Uninstallation is not allowed »

Issue:

I am trying to uninstall WithSecure Elements Agent (EPP for Computers or Computer Protection for Mac) from my Windows or MacOS computer, but I get the error notification: 
"Uninstallation is not allowed, Settings do not allow local uninstallation. Contact your administrator."

Resolution:

This is due to the Elements Endpoint Protection profile setting that disallows a user from uninstalling the product locally. 

Please ask your Elements account administrator to change the following setting to allow local uninstallation:

1. Log in to the Elements Security Center Portal: https://elements.withsecure.com
2. Expand the Security Configurations category
3. Go to the Profiles page
4. Select the profile that is assigned to the computer 
5. Go to the General Settings page
6. Enable to Allow the user to uninstall the product 
7. Click Save profile

Now you can uninstall Elements Agent locally from the device.

Note: On Windows devices Tamper protection feature is enabled by default in the Elements profile. This will block wsuninstallationtool.exe from running. 

If the above fails on a Mac and the uninstallation is still not possible, try the following.
Remove the following file using the terminal command below and try the uninstallation again:

In case of build version 38681 and newer:

• sudo rm /Library/F-Secure/fsmac/sysconfig/.no_uninstall

In case of older build version than 38681:

• sudo rm /usr/local/f-secure/fsmac/sysconfig/.no_uninstall

Note: This will require root permissions, should only be used as a recovery measure and will no longer be available in future releases of PSB Computer Protection.
