Default SMSC Uninstall

I'm trying to install the DisplayLink drivers, but it fails as it detects the SMSC drivers which were previously installed. I've uninstalled SMSC as much as possible, even going to using Revo Uninstaller to remove any trace of it, and still no use.

I've tried the compatibility check tool as well, and it doesn't create a log file in "C:\Program Files\DisplayLink Core Software\Debug\". In fact it doesn't even create the "C:\Program Files\DisplayLink Core Software\" directory, however it does create a DiCompatCheck.log file in the same directory I run the compatibility tool from. I've tried to attach it, but its regarded as an invalid file

Yes did all that. I uninstalled the ViewSpan software first and then SMSC Core Software (although it required Revo to do it fully). I've also checked and the folder SGFX folder no longer exists in C:\Program Files. Then tried deleting the services manually via CMD but they were already removed.

ie

Code:
C:\windows\system32>sc delete SGFXMgr
[SC] OpenService FAILED 1060:

The specified service does not exist as an installed service.


C:\windows\system32>

In case it helps I've posted the DiCompatCheck.log output to Pastebin

https://pastebin.com/dUyHiycE

Tried a few things, that didn't work, but the DlCompatCheck.log contents change, so putting up a new link just in case there's a difference when its decoded

No luck

Code:
C:\windows\system32>sc delete SGFX
[SC] OpenService FAILED 1060:

The specified service does not exist as an installed service.


C:\windows\system32>
I can do a "sc query >> c:\temp\service.txt" and then search through it for any mention of SGFX or SMSC or similar, but nothing shows up.

Is it searching through the registry for SGFX?.

Using the support tool, and searching for SGFX, I find the following section in setupapi.dev.log

Is there an option other than wiping and re-installing?

Got those files deleted now, and re-ran the support tool, but it still gives the same output. I'm thinking then that it has to be pulling this information from either a log file or else the registry?

Hello,

I'm sorry, I replied whilst on mobile and did not read logs properly.

HKEY_LOCAL_MACHINE\SOFTWARE\SGFX is detected. This is not a service, but the folder for the software itself, therefore you cannot remove it with "sc delete".
Do you need the command line or are you comfortable enough going in regedit to remove that?

Kind regards,
Alban
