Using Aida64 with bare G19 LCD, WITHOUT installing Logitech Gaming Software?

Recommended Posts

Question is basically as the title says. I have a G19 LCD by itself, only accompanied by the driver board; rest of the keyboard is gone. It worked fine on my old windows install, aida64 talked to LGS properly and I could get a picture up.

Now I have reinstalled windows, and I want to try and get aida64 to output to the LCD again, only without having to install logitech bloatware. Is this possible? I have the G19 driver installed and the device showing up correctly. Now Aida64 appears to look for a LgLcdApi.dll, which I also have, but I don't know where to put it. Is this all it needs; the .dll in the right spot or will it only talk through the LGS crapware now? Older versions of aida64 used to talk ostensibly directly to the G19 LCD before LGS was a thing, so it's concievably possible.

We've never tried it without installing LGS, so it would be an interesting experiment.  Place the LgLcdApi.dll file into C:\LgLcdApi\SDK\LCD\x86 folder.  Then using Registry Editor (REGEDIT.EXE) you need to add a new Registry value named InstallDir (type String) under:

HKEY_LOCAL_MACHINE\\Software\Logitech\Logitech Gaming Software

Set the value of InstallDir to:

C:\LgLcdApi

That should make AIDA64 find the DLL and try to load it.  We will then see whether it works or needs further components installed.

It detects the dll, but now it says "LCD Connect Failed". :(

So far as I can tell, whatever logitech had in the old dlls might have been moved into LCore.exe now, which is disappointing. With LGS installed it seems it won't talk to aida until LCore is running...
