Access to the path C:\xxxx\AssemblyCache\View_xxx.dll is denied

Hi All,

        I have created two new UNSAccount resources for DB tables. And created a BirthRightRole and assigned these two resources to BirthRight role.  I am assigning this BirthRight Role for all users. So whenever new user is created in Q1IM, BirthRightRole assigned and these two DB resources (DB_Res1, DB_Res2) will be assigned to the user. 

I have executed a batch job to create 10 new users into Q1IM, all 8 users were created well, but two users were not assigned the BirthRightrole and got following error:

2014-02-03 21:19:00 -06:00 - VI.JobService.JobComponents.ScriptComponent - 6123abcd-xxxxxx: Errors occured

    [810222] Error executing script 'VI_CreateAccountForRessource'.

    [810126] User accounts: Error applying dynamic template for Container on object  (DB_Res1).

    [810222] Error executing script 'Tmpl_UNSAccountB_UID_UNSContainerB'.

    [810028] Could not create the object referenced by Dell, Pattie (property Primary location).

    [810019] Could not create single object for table Locality.

    [810088] Error loading assembly C:\Users\processqimdev\AppData\Local\Quest Software\Identity Manager\AssemblyCache\View_abcd.dll.

    [System.UnauthorizedAccessException] Access to the path 'C:\Users\processqimdev\AppData\Local\Quest Software\Identity Manager\AssemblyCache\View_abcd.dll' is denied.

Then edited Q1IM user and manually updated one attribute on Q1IM users, then system assigned Birthright role as well as created two DB resources.

Version: Q1IM 6.1

Database: MS SQL Server

How can i fix DLL Access Denied error? Am I missing any configuration parameter?

thanks in advance
