Has anyone sen this error? I am trying to convert a 1.1 web app to 2.0 and this error is driving me to drink.
'CrystalReportViewer' is ambiguous in the namespace 'CrystalDecisions.Web'.

I have the save error. How to fix it?
This error drove me crazy for a few days. Basically it's telling you that there is still a reference to the old version of Crystal in the solution somewhere. After days of verifying that I didn't have any old references anywhere, the only thing that fixed it was deleting the website from IIS and re-adding it.
This may or may not work for you but hopefully will get you going in the right direction.
Your reply fresh my brain. I remove all reference of crystal report before conversion. There is no more error now. Thank you
Check the <assemblies> of the Web.Config. You probably have different versions of the same assemblies references listed in the file.
