I am trying to install Hitman Pro Alert but it keeps saying that this is managed by Sophos?

Question

I used this PC to test Intercept X, I thought I have removed it and I have bought Hitman Pro Alert Lic for the next 3 years and was planning to install it but once I hit install it tell me that this is "managed by Sophos"? and I can't install it. 
 Did I just waste my money buying the license if this beta test can not be uninstalled? 
 How do I get rid of this overlord?

Hi Pickle Rick 
 I would suggest you to check if the HitmanPro.Alert service still running in the client? In that case the client we can remove it via below options. 
 
 Administrative command prompt window run the following command: "<C:\Program Files (x86)\HitmanPro.Alert\hmpalert.exe>" /uninstall 
 Go to Sophos Central > Click Endpoint Protection> Click Computers> Click " Manage Endpoint Software"> On Left Pane , select " Intercept X"> You can see the list of computers Under " Assigned Computers" and you need to select that machine and move to left pane under " Eligble Computers" and click Save. 
 
 If the client service is not present in the client, try assigning permission's to authenticated user for C:\ProgramData\Sophos\AutoUpdate\Cache\decoded\hmpa64 folder. 
 Hope it helps.
