After I upgraded to latest version 4.11.2, I can’t open my reports, I’m getting invalid file format

Thanks

I compiled FRDemo with FR 4.11.2 and don't get such error

This error when you open old report created with previous version,
Now try this if you have old EmbedDesigner , create a report. Save it
Now try to open it with new compiled EmbedDesigner with new version you will get Invalid file format


Thanks

Attach your "old" report template

Here is the old one,

Also try to create one report with password (compiled version 4.10) then open it with new version and see if works.
May be something changed in zip and encrypt unit. I have to look and compare both versions

I opened your Test1.fr3 in FRDemo and EmbeddedDesigner demo (ver 4.11.2) without any problem

Did you add TfrxCrypt object in your project?
