Mapped network drives do not appear or work correctly

Mapped network drives do not appear

Issue:
Users are unable to see mapped network drives within software. However, the network drives are visible through Windows Explorer. Mapped drive do not install programs

Click Start, type regedit in the Start programs and files box, and then press ENTER.
Locate and then right-click the registry subkey HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.
Right click New, and then click DWORD 32Value.
Type EnableLinkedConnections, and then press ENTER.
Right-click EnableLinkedConnections, and then click Modify.
In the Value data box, type 1, and then click OK.
Exit Registry Editor, and then restart the computer.

This problem occurs because Windows 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.
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.

Problem:  When installing your Autodesk product, your installation fails and the resulting installation.log file on the summary screen (and your %TEMP% folder) shows the following error:

 

Install .NET Framework Runtime Language Pack Failed Installation aborted, Result=1603

Reason:  It is possible that the .NET Framework preinstalled in some Windows 7 and Windows 8 machines is not the full installation and the update for the language pack cannot install if a previous version or newer version is already installed.  This is a very similar issue in the past with the Prerequisite 1603 failures for .NET Framework and Visual C++ Redistributables failing.  This guide acts as a supplement to that article.
