Hi ,

I have an application in 2003 which I have converted into 2008. After compilation I get an error
The type or namespace name 'CrystalDecisions' could not be found (are you missing a using directive or an assembly reference?)      

But when I add the reference of the required DLL I still get the same error.

Can any one please tell me exactly where I am making the mistake.

Hi  johny_bravo1,

Actually, we have this application written in dotnet2003 from vendor who also gave us the code. Now we to have optimize the performance and update it. We have 2008 on our machines. No one actually till date actually tried debugging on the 2003 version. Therefore I am facing this problem.

Are you suggesting that I should have dotnet2003 software also on my PC?

Hello Sri..

If you are developing an application using one of the Crystal Reports SDKs for Visual Studio, you need to deploy the Crystal Reports Runtime on each computer where your application is expected to run.

I think Since you upgraded, you probably have more than one instance of CrystalDecisions.CrystalReports.Engine in the GAC.  What you need to do is add the assembly information to your local web.config.  

<system.web>   <compilation ....>      <assemblies>         ....         <add assembly="CrystalDecisions.CrystalReports.Engine, Version=x.x.x.x, Culture=neutral, PublicKeyToken=[Your PKT]"/>         <add assembly="CrystalDecisions.ReportSource, Version=x.x.x.x, Culture=neutral, PublicKeyToken=[Your PKT]"/>         <add assembly="CrystalDecisions.Shared, Version=x.x.x.x, Culture=neutral, PublicKeyToken=[Your PKT]"/>         <add assembly="CrystalDecisions.Web, Version=x.x.x.x, Culture=neutral, PublicKeyToken=[Your PKT]"/>         ....      compilation>   ....</system.web>

Hi sree_ven,

I have tried installing the CRRedist2008_x86.msi  but  there is no change in the error. Infact now it is giving error as

The type or namespace name 'Web' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)


Surprisingly these entries are already present in the web.config file.

Can there be any other reason.

Hello Sri
Check the references in the Controls. Look at the Microsoft.Web.Atlas reference. It may have a warning sign in the icon. This means that the reference is not found. Delete the reference and make a new reference to the assembly. You need the to Atlas bits that contain the assembly.
