Could not load file or assembly ‘Microsoft.ReportViewer.Web” v11.0.0

Question

User438705957 posted

I realise this is a common thread but can't get the info I need.

I developed my web app in ASP.Net 3.5 and used Crystal Reports in VS to develop the reports.

I have now confirmed that the version of Crystal compatible with 3.5 does not support IE 11.

I am now developing a new suite of reports in reporting services to be compatible with the rest of the organisation.

I have upgraded to VS 2013 and in order to support the 3.5 Production website, have set the target .Net version to 3.5. in VS.

The reporting services reports I developed in development work beautifully but when migrating the reports (and web.config) to prod I am getting the dreaded
"Could not load file or assembly ‘Microsoft.ReportViewer.Web” v11.0.0"

So here are the questions:

1. What version of the report viewer assembly will be found by the 3.5 production environment and how do I go about installing it.
2. In lieu of the approach in 1. working, Are the v11 versions of report viewer compatible with 3.5 and how do I go about installing them.

Please don't tell me I have to mess with the GAC, as I have no permissions on the production box, and the ops crew have no stomach for it.

Thanks
