.Net 4.0 Runtime Engine Prerequisites

[Former Member]

Hello.

What .Net framework version does the u201CCrystal Reports Runtime Engine for .Net Framework 4u201D needs in order to function correctly?

My guess would be that it only needs .Net 4.0 but the application that we use to package and distribute our application wants to include the .Net 2.0 as well. This is probably a bug in the package and distributing application but I wanted to double check with the expert.

Thanks.

Hi Rene,

Not a bug, CR still requires 2.0 Framework for legacy components so it will need to be included as a prerequisite.

Thanks guys.

Ludek: Thanks for the link but I was unable to see anything on that page that mentioned needing the .Net 2.0 framework. Did I miss something?

Don: When I install the Crystal Reports run-time engine on a clean pc with no .Net frameworks installed, I get the following message:

This software package can only be installed on systems that has installed .NET Framework 2.0 or higher.

This message leads me to believe that the Crystal Reports run-time engine is basically based on .Net 2.0 but forward compatible with .Net 4.0.

I am thinking this because I don't think that it is possible (at least I don't know how to do it) for an application to use .Net 2.0 and .Net 4.0 at the same time. So if my application is based on .Net 4.0 and that is from where I run my Crystal Reports, do I really still need .Net 2?

Thank you.
