Adobe Premiere Pro 2024. I can't install video adapters

In addition to what Peru Bob asked, please note that older Intel and Nvidia hardware are now no longer supported any more in this latest version of Premiere Pro. Specifically, Kepler CPUs such as most of the GeForce 600 and 700 series are no longer supported as these GPUs are in legacy support status at Nvidia itself. Adobe requires driver version 522 or higher in order to be compatible with Premiere Pro, but Kepler GPUs'  driver version only goes up to version 474.64 (at present).

And integrated Intel GPUs of the 6th- and earlier gen GPUs are now no longer supported by Adobe any more as Intel had completely discontinued all support for those CPUs back on December 30 of last year, and the remaining 7th- through 10th-Gen Intel CPUs are already in legacy support status with 7th-Gen CPUs' support scheduled to end completely in March of this forthcoming year. This is reflected in the "recommended" system specs officially listed on Adobe's Web site, which now officially recommends an 11th-Gen or newer Intel CPU.

What are the complete computer specs, including hard drives (how many, what kind, what is on each, what capacity, and how full)?

Make sure to use the latest Studio Driver from NVIDIA (NOT the Game Driver).
