compatibility problems between FR5 and FR4

Matthias Kosarek

Hi,

when I create a report in the designer with FastReport 5 and I try to open it in a program which is using FastReport 4 I get the following error:

"The following error(s) have occured:
Cannot find class Datasets"

When I open the report in the designer with FastReport 4 and I try to open it in a program it is working, no matter if the version is FR4 or 5.
When I open the report in the designer with FastReport 5 and I try to open it in a program which is using FastReport 5 everything is working fine.

Are there any compatibility problems when creating a report with FR5 and open it with FR4?
How Can I save the reports in the "old" format.

Thanks and regards
Matthias

FR5 have a new features, FR 4 don't know about these features, so this is expected behavior

Open FR5 report in the FR4, ignore all error messages and save it in the FR 4
