This is very interresting, i installed the latest version just nowas you can see on the first screenshot… then i am trying to do a benchmark test,and it says i must install D5 2.8 or above. must be an installation issue please see screenshot
Hi @riki Thank you for providing the screenshots. Devices with certain CPU models such as Intel Core i9-13900K/KF/KS and i9-14900K/KF/KS are known to cause similar issues.
I recommend updating your BIOS version from the motherboard’s official website and turning off CPU overclocking as well. Please you can proceed with the installation of the new version 2.9 after the update. Kindly reach out to us if the issue persists.

Hi, I also encounter problem after installing version 2.9. Please see my screenshot.
I use MSI Cyborg 15 A12V with the following spec:
Processor 12th Gen Intel(R) Core™ i7-12650H 2.30 GHz
Installed RAM 32.0 GB (31.7 GB usable)
System type 64-bit operating system, x64-based processor
Graphic NVIDIA GEFORCE RTX 4050 Laptop GPU
Hi there, apologies for the inconvenience. Kindly restart D5 as administrator and see if the issue persists. Were you able to use version 2.9 at all after updating or this issue started right after updating?
Hi Anthony
unfortunately not able to use D5 at all, issue started right after i updated to 2.9
i tried everything, cant even roll back to older versions, it just does not open any files
Hi @riki, please could you share a copy of your log file to our mailbox support@d5techs.com for further examination. Kindly use the tag Anthony_forum_2.9 in the email, we hope to resolve this issue as soon as possible.

Hello @reza
Sorry for the issue. Just for confirmation, can you use D5 2.8 or previous versions normally before? Did this problem occur suddenly after upgrading to 2.9?
Please ensure the ‘Hardware-accelerated GPU scheduling’ is disabled.
Hello @riki
Sorry for any inconvenience caused.
Just want to know, have you tried Anthony’s suggestion of updating your BIOS version?
We recently had a known issue related to specific CPUs and yours is exactly the Intel Core i9-14900K. The latest BIOS version may fix related bugs.

Hi Leah,
Yes, previously I have no issue, it works normally. The issue occur after I update to the newest version.
I disabled ‘Hardware-accelerated GPU scheduling’ but the problem is not solved yet.

Oh, great news, thank you for the updates.
Hi @vbo2
Just for confirmation, are you using Windows High-contrast themes ? Or are you using
plugins like Mica For Everyone ? Please turn them off and try again.
@Leah_Li I have no Contrast theme on. Also I updated BIOS and all other updated on my computer, and disable the Hardware Acceleration, and still not working.
The small window on the windows bar shows the d5 screen working, but the program window is black. If I add a scene on D5 it also shows the normal image on the thumbnail, while d5 screen is black
@Leah_Li I also tried collecting the Log files from D5, and it shows there is a conflict with AlienFXSub Agent. Is that the problem? Whats the fix?
Hi @vbo2
Thank you so much for the detailed information.
Can you try to disable this conflicting software and check the result again?
