Any idea why this appear?

Answer 1

The "load report failed" error message can be caused by several factors:

1. crystal report is not properly configured on your machine
2. crystal report assemblies installed on your machine do not reflect the assemblies you have on your web.config
3. crystal version installed on the server is different with the one you want to invoke from your site
4. application pool where your reports run is not set to LOCAL SERVICE
5. read and write permission is not enabled on your root folder
6. crystalreportviewer folder is not copied to your operating folder.
