Thank you Ludek, this answer and your blogpost were clarifying.
Our problem, however, is a little different.
We currently use Crystal Reports 10, because that is what our vendor application supports for generating its reports.
An upcoming vendor release uses SAP Crystal Reports 2008. We were told that we will need to open all of our Crystal files in CR2008, verify, run, and save them in order for them to work with the new version.
My question is: if the 2008 runtime has not changed between 2008 and 2013, can we purchase SAP Crystal Reports 2013 instead?
That is, can we open and convert all of our old Crystal 10 files using CR2013, and expect that our vendor application (using the 2008 runtime) will still generate reports appropriately?
