Access denied when I try to install profiler - dynamics-crm

Question

As the subject says, I am having an issue trying to install profiler through Plugin Registration Tool. I can do all actions on plugins from registration to disabling them. 
I am using Microsoft Dynamics® CRM 2016 (8.1.0.359) (DB 8.1.0.359) On-premises, and Registration tool version is 8.2.1.8676 64bit. 
What I have tried:
I tried tp install profiler in Dev, and staging environment but no luck!
I tried to install it on 100% running plugins and still same issue.
Any idea how to solve this problem or an approach to find the source of the problem?
Note: I am a system administrator and deploy admin too. 
Many thanks,

Answer 1

We were able to solve this thanks to Jens #Dynamics-community
The solution was by modifying the permissions to folder c:\Program Files\Microsoft Dynamics CRM\CustomizationImport.

Thanks all,

Answer 2

have you tried to downgrade the version of the profiler you are using? Going from 8.1 to 8.2 has quite a big gap on the functionalities that have been changed.
If you are on premise are you sure you have the correct AD groups assigned to your user? Is not enough to insert your user in the deployment admin tab in the deployment manager.

I faced the exact issue, What worked for me is Installing Plugin profiler with Dynamics CRM Solution. You will have a .zip file with name "PluginProfiler.Solution.zip" for plugin profiler. Try importing it and should work.
Let me know if it works for you
