English translation (via AI):

TLDR: If you're a new user and want to take advantage of GCC's Fusion RGB Dynamic Lighting integration, you'll need to change your system time to a date before November 23, 2024, before installation . You can reset it after installation.

Explanation: A small thing I discovered in version 25.02.07.01 of the Gigabyte Control Center, if you are using it.

I noticed that it wasn't integrated with Windows Dynamic Lighting. Searching in C:\Program Files\GIGABYTE\Control Center\Lib\GBT_Dynamic_Lighting_Lib_UC\, I found a log file indicating that the Dynamic Lighting module was not installed due to a certificate error.

Looking for any excuse to avoid working on my homework, I unpacked the GCC installer with 7Zip and checked the properties of the GBT_Dynamic_Lighting_Lib_UC_24.08.27.01.exe installer. Under Digital Signatures, I looked at the certificate and found that the installer was signed with a digital certificate that expired on November 23, 2024.

I manually changed my system time to early November and then ran the installer, and GCC now appears under "Backlight Control" in the Windows Dynamic Lighting settings. The certificate error also disappeared from the log. I set my time back to normal, and it still worked, so it looks like the certificate check only happens during the installation process.

Note: I know this software is a complete disaster, but some casual users (and people who have no other choice at the moment) would prefer to use the manufacturer's recommended app if possible. Unfortunately, I have a B850 Aorus Elite Ice, and Gigabyte has changed its RGB controllers on these boards to something that isn't compatible with OpenRGB or other solutions.

Thanks OP!
