.Net Framework 2.0 and Microsoft CRM 3


So a question I see about once a week is about .Net 2.0 Framework being installed and how do you get CRM to work in that enviroment… Believe it or not, it is documented… 🙂 But for those of you who will refuse to read the whole IG… Here is the cliff notes from Irene… 🙂


.NET Framework 2.0 can coexist on the same machine with .NET Framework 1.1. The Microsoft CRM v3.0 web site needs to be set to use 1.1.



1.       On the Microsoft CRM server, point to Start, point to All Programs, point to Administrative Tools, and start Internet Information Services (IIS) Manager.


2.       Expand the node for the computer, and expand the node for Web sites.


3.       Select Microsoft CRM v3.0 Web site, and then on the Action menu, click Properties.


4.       On the ASP.NET tab, in the ASP .NET version box, select 1.1.432, and then click OK. Note that this tab is only present after you install .NET Framework 2.0.


5.       Expand the node for the Microsoft CRM v3.0 Web site.


6.       Select MSCRMServices, and then on the Action menu, click Properties.


7.       On the ASP.NET tab, in the ASP .NET version box, select 1.1.432, and then click OK.


8.       On the Start menu, click Run, and then type iisreset.

    I would have tried this solution, the only problem is I cannot choose any other version of .NET than 2.0.50727

    You can reinstall .NET Framework 1.1 then select it for your CRM IIS needs.

    If you still need to run 2.0 sites (say you have SQL Server 2005 Reporting Services installed) then am I right that you also need to make sure that you run the 1.1 and 2.0 sites under different AppPools, and each AppPool with different accounts?

  4. Eu gostaria muito de vos dizer algo acerca do produto mas o ´facto é que nunca o usei.

    Muito obrigado e muitos cumprimetos. António Batalha.

    Whenever I set the Microsoft CRM v3.0 website to .NET v1.1, reset IIS, and I try to browse to it, it gives a 404 error and says page cannot be displayed.  When I switch the site back to v2.0, reset IIS, it starts working again but i get the Reports.config has invalid schema, and could not be loaded.  error when going into Reports.

    suggestions?
