Answer 1

Crystal often gives you missleading error messages.

In my case I've set Copy to Output Directory of *.rpt file to "Do not Copy" (like you have it too) and I was passing the file path to the bin folder (where it doesn't exist) to ((ReportDocument)rpt).Load("[/bin/folder/path/report.rpt]");

->So check if the file(path) you want to load really exist

My Build Action is set to Embedded Resource (was default)

Use runtime path for loadding report I.e reportDocument.Load(Application.StartupPath + "\CrystalReport1.rpt");

Make sure report files are placed in specified folder which is directed by this path. use string str = Application.StartupPath; to be sure that which folder it refers to then place report files in this folder it will work fine. I faced similar problem like you and then I noticed this path indicates to bin\debug folder while report files in my project were somewhere else I just copied all files to debug folder and its working fine .... cheers

In my case, it was a problem with permission. Check if all users are allowed to access the file.
