Hi Jan
2 posts above I described the way I do, I post again these steps:
Uninstall v2010.2,then manually removed all Stimul folders from c:\WINDOWS\assembly\GAC_MSIL\
Then I install only Stimulsoft Reports.Net 2010.3.msi,I delete old dll report file then save my report to new dll file,no erro
In my application removed old references and added new as in image.
Run the application but when I must see the report I see this :

going back to version 2010.2 all works fine,there must be something changed from 2010.2 to 2010.3 that I miss ,what I do wrong,pleas help me :dumb:
Thanks.
