When you log in to Novell SSL VPN an error is displays as "An error occurred installing the TAP-Win32 device driver".
To workaround this issue:
Go to Start > Run.
Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion.
When CurrentVersion is highlighted, go to Edit > New > Key.
Enter the key name RunOnce.The RunOnce key is added below the CurrentVersion key. Once the key exists, Windows 2000/XP stops re-detecting the hardware
NOTE:This error occurs only if the RunOnce key does not exist in the system. If the issue still exists, then after adding the RunOnce key restart the system.
