Nvidia Driver not Installing - The required line was not found in the INF

[Azjon]

It's weird I have 6/7 cards running.  It shows the 7th gpu in device manager but its not installing the driver.  I tried having the system automatically install the driver with no luck.  I manually tried installing the driver to the 7th gpu and i'm getting the error "The required line was not found in the INF".
One by one i'm able to get all the gpu's working except the last one.  Currently I have just the 1 gpu connected to the mobo (via riser) and i'm still getting the "The required line was not found in the INF".

I've attempted to install Nvidia 388.61 and Nvidia 390.77 drivers.

Setup:
7x - MSI 1070 Ti Titanium
Windows 10
4 GB Ram
Mobo:  Asus z270-A
CPU: G4400
