see mapped drives in old prog win 10

Symptoms

Mapped network drives are not visible when creating PDF files from Primavera on Windows Vista and Windows 7 when the User Account Control (UAC) is enabled.

Cause

This problem occurs because UAC treats members of the Administrators group as standard users. Therefore, network shares that are mapped by logon scripts are shared with the standard user access token instead of with the full administrator access token.

Solution

Configure the EnableLinkedConnections registry value, which allows Windows to share network connections between the filtered access token and the full administrator access token for a member of the Administrators group.

To configure the EnableLinkedConnections registry value, follow these steps:

1. Click Start, type regedit in the Start Search box, and then press ENTER.

2. Locate and then right-click the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

3. Point to New, and then click DWORD Value.

4. Type EnableLinkedConnections, and then press ENTER.

5. Right-click EnableLinkedConnections, and then click Modify.

6. In the Value data box, type 1, and then click OK.

7. Exit Registry Editor, and then restart the computer.
