I have a software developed with micrsoft visual studio 2010, mysql and Crystal Reprot for vs2010 (13.0.10). When I run the application on Windows Server 2012 R2 (64Bits), generates an error: Can not load the database. The data I have them in a dataset but not displayed. Reportviewer opens the vacuum. Now install the merge modules and XML driver, the machine vistual java, I tried everything, but nothing works. Not to do. I appreciate the help if someone already happened by this problem.
