"Failed to update the system registry. Please try using REGEDIT"

Jan 24, 2018
We have a scheduled task (Windows Server 2012 R2) that calls a tcc.exe window and passes it a .bat file. This task has been running successfully for a while now as a domain admin account. When we changed the task to run as a non-domain admin (still a local admin) account, the task no longer runs. When we call tcc.exe and pass it the .bat file from command prompt we are presented with the following error message: "Failed to update the system registry. Please try using REGEDIT". I'm sure this is a permissions issue, and I have checked the following Reg permissions with no success:
  1. HKEY_LOCAL_MACHINE\Software\Oracle
  2. HKEY_LOCAL_MACHINE\Software\Classes
  3. HKEY_LOCAL_MACHINE\Software\Classes\.DIS
  4. HKEY_LOCAL_MACHINE\Software\Classes\Dis.Document
  5. HKEY_LOCAL_MACHINE\Software\Classes\Discoverer.Application
  6. HKEY_LOCAL_MACHINE\Software\Classes\DIS
  7. HKEY_LOCAL_MACHINE\Software\Classes\CLSID
  8. HKEY_LOCAL_MACHINE\Software\Classes\CLSID{470A152C-5FC1-11D1-A434-0000F8AE4944}
  9. HKEY_LOCAL_MACHINE\Software\Classes\CLSID{AD7CE4E0-C391-11CE-9C10-08002BE52B53
Please help!

Two things to check:

1. that the task has "run with highest privileges" checked.

2. that the domain admin had not restricted the local admin my means of a group policy object.

Thanks for the replies! The issue was simple - I was still logged in as domain admin when I changed the task to run as the new user, and "Run only when user is logged in" was checked. I also had to check "Run with highest privileges".

TL;DR - Make sure you're logged in as the user you need the task to run as.
