Crystal Reports keeps giving me: Could not load file or assembly

So I have a C# website that I have to work with. It uses crystal reports so I installed it (First time working with crystal reports). I came across the following error while trying to run the website

Could not load file or assembly 'CrystalDecisions.Enterprise.Framework, Version=11.5.9.1229, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

These are the logs :

I've tried various things and searched the internet for answers but so far nothing worked.
