Could not load file or assembly System, Version=2.0.5.0 due to the referenced assembly targeting .Net Framework 3.5

Question

I have a project which is running on .Net framework 4.5. But it has a reference to a dll which is targeting the .Net framework 3.5 in which it has reference to mscorlib and system dlls. While running the code I am getting exception as Could not load file or assembly System, Version=2.0.5.0.

I have seen the below article which is similar to my problem.

Could not load file or assembly System, Version=2.0.5.0 in .NET 4 MVC 4 application

But the patch whichever mentioned ((KB2468871)) doesn't working for me. When I try to install it's showing the message as "KB2468871v2 does not apply, or is blocked by another condition on your computer."

I don't have control on the referenced assembly to change the framework.

So Can anybody please help me to solve this problem?

The error "KB2468871v2 does not apply, or is blocked by another condition on your computer." come mostly from low disk space, make sure you have at least 2 GB free disk space before running the update, make sure you reject all removable devices also. If it does not work, try going into Control Panel --> "Uninstall a program" and click on "Microsoft .NET Framework 4 Client Profile", then select "Repair .NET Framework 4 Client Profile"

I couldn't find anything related to "Microsoft .NET Framework 4 Client Profile" in control Panel. – Chandra Mohan May 05 '16 at 12:32
In fact, it's Control panel --> Uninstall a program. Try to repair "Microsoft .NET Framework 4 _anything_" if you don't find "Microsoft .NET Framework 4 Client Profile" – Zakariaa.B May 05 '16 at 13:11
All I can see 4.5 related things. I am working with vs2013. Current project framework is 4.5 and one of the dll has a reference to .Net 3.5 – Chandra Mohan May 05 '16 at 13:39
Yes, sorry i meant 4.5. – Zakariaa.B May 05 '16 at 14:00
It's not solved the problem. Still I am getting the same – Chandra Mohan May 05 '16 at 14:25
Try to install the update now, please check that you have 2 GB free disk space in C: disk – Zakariaa.B May 05 '16 at 14:34
No luck. still same issue with the patch also – Chandra Mohan May 05 '16 at 15:15
It means you no longer have this error "KB2468871v2 does not apply, or is blocked by another condition on your computer." ? – Zakariaa.B May 05 '16 at 15:19
