Side by side error

1 year ago, I was using SW on my pc using W8. One day it stopped working due to a side by side configuration error. I tried fixing the problem without success. Now I am using W10 x64 bit and the program still doesnt work. So I am coming to you guys for help, bearing new information. I used event viewer to see what the problem was. This is what is showed me :

La création du contexte d’activation a échoué pour « C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\sldworks.exe ». Assembly dépendant Microsoft.VC90.ATL,processorArchitecture="amd64",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.30729.6161" introuvable. Utilisez sxstrace.exe pour un diagnostic détaillé.

I tried using sxstrace.exe for a deeper diagnostic, but that program doesn't work either. I have SW studient version SP2.1.

Welp please
