I got my 1-year licence key for Solidworks yesterday. I downloaded and installed SW 2018 SP03, when i tried to open it, splash screen came and says "Loading registry, Verifying Licence" and disappeared. I deleted it and downloaded SP05 and it says same thing. My system is not the best but i was able to use SW 2017 one year ago.
Lenovo IDEAPAD 300
AMD R5 M330 - Intel HD Graphics 520
8 GB RAM
Windows 10 PRO
Edit : I've solved my problem. I disabled one of my display adapters ( Intel ) and i am able to run SW right now.
Edit2: I've updated my graphic card's ( AMD R5 M330) driver and problem solved.
