======Error message: VPOP3 does not have write access to the registry - please check and restart VPOP3====== VPOP3 needs to be able to write to the Windows Registry at **HKEY_LOCAL_MACHINE\Software\PaulSmith**. Usually, VPOP3 will run in the 'Local System' user account which has full permission to the HKEY_LOCAL_MACHINE part of the registry. However, it is possible to lock down permissions further, or to run VPOP3 in a different user account. In that case, you may encounter this error message. To do this, run RegEdit, find the **HKEY_LOCAL_MACHINE\Software\PaulSmith** registry key (if it does not exist, create it). Right-click that registry key, and choose **Permissions**. {{:how_to:regperm1.png|}} Then, give the account which VPOP3 runs in, 'Full Control' of the HKEY_LOCAL_MACHINE\Software\PaulSmith registry key and sub-keys. If VPOP3 is running as the 'Local System' then you need to give permission to the **SYSTEM** user. Once you've done this, you will need to restart VPOP3.
