Netscreen Remote 8.7 failed to install Deterministic Networking (DNE) drivers.  Seeing "No Driver Installed" message on task bar icon.

When installing Netscreen Remote 8.7 you will get an error when the Setup attempts to install the DNE drivers.  You will see an error similar to below:

"The specific path does not contain any applicable device INFs"

NSR version 8.5 and 8.6 also fails to install.  Following the DNE uninstall process fails to correct the issue.  The issue was occurring on brand new out-of-the-box PCs with no other VPN applications installed.

For the record, the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DevicePath value should be a REG_EXPAND_SZ value. The machine that was failing install was configured with a REG_SZ value, and so environment variable expansion was not performed.

Apparently, the DevicePath value was updated for some sort of Smartcard support package, and this resulted in the bad type.

The tell-tale symptom (outside of the install failure) was that the Network Control Panel applet would report the error "The specific path does not contain any applicable device INFs" when an attempt is made to initiate installation of any network Client, Service, or Protocol.

By re-creating the DevicePath with a REG_EXPAND_SZ type, the install worked.  The above noted modified registry key was the reason the client could not install correctly. The correction should allow the client to install properly.  So it appears the issue was a change made by Microsoft. To resolve the issue you will need to go to Regedit or something similar and make the necessary change to the Windows Registry as outlined above.
