Hozawa, That is a valid point, however, I downloaded the file (TIB_js-jss_7.2.1_windows_x86_64.exe) on March 21, 2019. I downloaded the JasperReports.IO eval on the same day. The JasperReports.IO instance runs all the sample reports. But I can't use Jaspersoft Studio to preview any of my own reports. This makes no sense. I have submitted this question also to the TIBCO "Contact Us" page and they simply referred me here to the community. This is frustrating and it seems TIBCO could care less that I am able to properly evaluate their product.
