Dynamic CRM Solution Deployment – Fix Access is Denied issue while importing CRM solutions

While importing CRM solution using Async service (CRM solution automated deployment), CRM copy the solution file (zip file) to the temporary directory with Guid (unique id). That temporary directory located inside of CRM installation directory. For example in our case it located in “C:\Program Files\Microsoft Dynamics CRM\CustomizationImport”. When we enable the trace using CRMDiag Tool it shows error in async service log like following. 

>Crm Exception: Message: Access is denied., ErrorCode: -2147187707, InnerException: System.UnauthorizedAccessException: Access to the path 'C:\Program Files\Microsoft Dynamics CRM\CustomizationImport\82c98e8896b34b2cb60e7741971a7921' is denied.

How to fix:

The root cause of this issue is user who run the CRM Async service does not have write permission to the CRM Customization Import directory (in our case “C:\Program Files\Microsoft Dynamics CRM\CustomizationImport”). To fix this issue give necessary permission to the user who runs CRM Async service.

Identifying user who run CRM Async service

Navigate to Services -> Microsoft Dynamics CRM Asynchronous Processing Service, then check Log On As

Set permission to the user
