Cannot open .rpt Crystal Reports file in Visual Studio 2010

Question

I have taken over an existing C# project and am using Visual Studio 2010 with .NET framework 4.0.

The application uses Crystal Reports. It seems like the definitions

Answer 1

I suspect the file-type association for .RPT is broken. You may have tried opening the .RPT before you had Crystal Reports installed and accidentally selected something else to open it. Now it probably automatically opens them incorrectly.

This article describes changes between Windows versions and how to edit them: http://www.technize.com/advanced-file-types-association-in-windows-7/

That said, there is a quicker easier way to do a quick test to confirm if those .RPT files are valid.

In Visual Studio, inside your C# project, do an 'Add New Item > Reporting > Crystal Reports' and it will start a wizard for adding reports to your project. When this happens, you'll be prompted to 'create a new report' or to 'open from existing file'. Choose open existing and browse to your .RPT file. This should force Crystal Reports to attempt to open this file in the Visual Studio based Crystal Report designer.

Best of luck with it.

Answer 2

Problem: On a 64-bit machine with Visual Studio 2010, I had installed the 32-bit version of CRforVS.

Solution: I needed to install the 64-bit version of CRforVS.

That's funny, because as far as I know, all versions of Visual Studio are 32-bit.

Answer 3

According to information from: http://scn.sap.com/docs/DOC-7824

Note 1: To integrate "SAP Crystal Reports, developer version for Microsoft Visual Studio" you must run the Install Executable. Running the MSI will not fully integrate Crystal Reports into VS.MSI files by definition are for runtime distribution only. By default Windows 10 does not install the 3.5 framework, CR for VS still needs it. Select it by "Turn Windows feature on or off" and choose both options.

Note 2: SAP Crystal Reports, Developer Version for Visual Studio .NET does NOT support Express Editions of any version of Visual Studio .NET.

Answer 4

For development, you need to install SAP Crystal Reports, version for Visual Studio 2010 - Standard from the download page you linked to.

The Click Once version that you installed is for deployment.

Answer 5

I have had similar instances on a 64-bit machine, where I designed the crystal reports in a given User Profile, and When I changed to another User Profile on the same Computer, Crystal Reports Seemed to be broken.

Solution: I solved this by re-installing Crystal Reports for vs2010 (64-bit) on the other User Profile also. Looks like when you install CR on a computer with many User Profiles, you may want to select Install for Everyone, instead of just me.
