"Error 1606: Could not access network location" when performing unattended installation

Oct 31, 2014


When you performed an unattended installation using Group Policy Objects (GPO) or System Management Server (SMS), you received the following error message in the Windows Event Viewer or installation log file:

Error 1606
Could not access network location <Path>


This error can occur if the SYSTEM account in Windows is unable to locate user-specific folders during the unattended installation.

To ensure the SYSTEM account can find the folders it needs, make sure that the following registry value is set to a valid location and that the SYSTEM account has Full Control permissions.

HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders


Name | Value

Local Settings | C:\WINDOWS\system32\config\systemprofile\Local Settings

Local AppData | C:\WINDOWS\system32\config\systemprofile\Local Settings\Application Data

Note:  The values for the above registry entry may vary from machine to machine, and are intended to serve as examples only.  If you are unsure which values need to be adjusted or how to adjust these values, contact Microsoft or your system administrator. A separate update was designed specifically for AutoCAD® 2004. The related update only applies to AutoCAD 2004, but this solution is valid for all supported versions.
