I am trying to implement report viewer for the first time and I am having trouble nailing down the issue. I am getting this error:

Could not load file or assembly 'Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified

I am using Studio 2008 on a Windows 7 64bit. The development website is on a 2000 Server. Server shows .net 1.1 and 2.0 installed. I can only see configuration manager for 1.1. I installed the reportviewer on the server and it says it was successful but I can not find the dll's. I looked in the registry for reportviewer and found several entries and all of them say it is version 8.0.0.0.

I've been reading blogs and MS Knowledge Base articles til I am crosseyed. They all just basically tell me to install .net 2 and the reportviewer which I have done already. Hoping someone out there went through the same issue and has ideas before I abandon and try to learn crystal reports in a night.

Is this happening when you have it deployed and ran or happening when you run it from your local machine in debug?

Clicking view in browser and web address shows development server IP and page hierarchy.

I got it working locally now but not on server. Server error codes stating it wants .net 3.5
It's my understanding that my 2000 server won't support 3.5.
We are planning to upgrade dev to 2003 in the next month or so I guess project is on hold until upgrade.
Thanks for advice/questions up to this point.

Well that sucks... and seems odd. I would figure 3.5 would install on most any windows os's... though it is twelve years old. Hmm. Keep us posted.

I changed over to a 2003 server, Production was on 2003. Took a mirror and built a quick and dirty dev server. Installed .net, report viewer, etc and it all worked. During these tests, I was using a view as the data source. I just changed over to a stored procedure and it isn't working and I am not getting any errors. Going to start a new thread and attach what I have so far. Thanks Modi123_1 for your interest and assistance.
