Best Answer

I think you require this code, add it into your web.config

<startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>

Pretty sure this is on google, it maybe a duplicate (will search after answering)

EDIT:

You may have to edit your .Net setting within your build configuration. Maybe try uninstalling the crystal assemblies - set .Net 4 and reinstall (assuming you weren't already on .Net 4) – n34_panda yesterday
