Recently I wanted to install AutoCAD on my pc since I was learning landscape so I installed the 2026 version first and it was heavy on my pc so I uninstalled it and tried an older version 2023 but when the setup is in process it stops and give me the error code 15 after that I tried and searched every where to solve this problem but it didn't work how much I tried i even tried installing 2024 and 2026 again but still the same thing.
My Pc specs (if anyone wants to know): I5 6500 8G Ram R5 450
