I am trying to run TLC II on my HP, and get the error efk_usb library not found! I have attached a screenshot.
I am on windows 11, currently up to date. I have the VC redistributable package installed, TLC is installed on the default C: drive location, I have the USB drivers downloaded and installed to my Xpress512 which V9 can see and interact with, and everything else is up to date. I am on the latest version of the software that downloads from the link. I am unable to move past the screen and TLC closes itself if i click anywhere on it.
I'm on a HP workbook, Intel ultra 7 255U processor, Intel Graphics software, 32 GB DDR5 Ram, and am the admin account.
Please advise how to move forward.
Thank you!

Re: efk_Library not found 2026
Hello,
Thank you for this clear report.
There is effectively a problem with this new version.
Sorry for that.
We put back the previous version (0.1.37) on line.
And we will work on that problem.

Hello,
We will put on line a new version which fixes this problem asap. In the meantime, if you unzip this file: https://download.thelightingcontroller. ... ftd2xx.zip
and you add the file "fdt2xx.dll" in the folder of the software, the new version 0.1.38 will work
Actually
The previous software version 0.1.37 is here: https://download.thelightingcontroller. ... indows.exe
The new software version 0.1.38 is here: https://download.thelightingcontroller. ... _v0138.exe
The missing file for v0.1.38 is here: https://download.thelightingcontroller. ... ftd2xx.zip
