I tried to instruction from this link but it it's outdated and doesn't seem to work for Windows 10:

I added the custom vendor string as described (see the attached INF file) but when I try to install this driver, I get this message:

The hash for this file is not present in the specified catalog file.

I Googled this issue and turns out I have to use Inf2Cat.exe to generate new .Cat file.  So I did….. using this command:

C:\Program Files (x86)\Windows Kits\10\bin\x86>Inf2Cat.exe /driver:C:\cypressWin10 /os:10_x64


Signability test complete.





Catalog generation complete.



But this time I get this message on driver install:

A problem was encountered while attempting to add driver to the store.

And in System Events I see "Problem signature:

P1: x64

P2: USB\VID_04B4&PID_00F9&REV_0000   <---  this is my custom vendor ID

I Googled this too and basically it sounds like now I have to sign this driver using SignTool.exe.  But I need some PFX file and I don't have it:

​Could someone please let me know if I'm on the right path and if yes, where can I get this PFX file?  Thank you!
