Error running older versions of CR when application upgraded to RDC 11.5?

Why can't we run older versions of Crystal Reports (versions 8 and 9 were tried) when the application we are using them in upgraded to use RDC 11.5.

The application had support for CR 11 before they upgraded to the RDC 11.5 and we were able to render CR 8 files (rpt). With the upgrade though, if we save our report files to CR 11, they run but otherwise we get "error 9 subscript out of range". We did not try version 10 rpt files.

Any insight? I've researched the web but not too familiar with the RDC (I did read that it is depracated after 11.5) so I am not sure if I am just missing it or not understanding what I am seeing. Can you only view the version [of the report file] that the RDC was created for? and if that is the case, does that mean just major versions - seeing as 11 R1 [report file] runs after the upgrade to 11.5?

    • Hi CR DEV,

      Thank you for the info, much better. If the third party software company said you can't do it or they don't support it then you'll have to upgrade accordingly. There are multiple reasons why their software may not support older versions but that depends on what they do in their application. They could be using functions that are no longer available and therefore had to open the report in a different manner and apply changes differently or what they had to do is no longer capable in RDC. Can't say for sure without knowing what they do or did.

      Technically there should not be any issues opening even 8.5 reports in any of our versions, other than earlier versions than 8.5. From 9 onward all our versions will open previous versions and should not be any problems. But this is a generic answer, we do have import routines that convert older reports to the latest format and used while the report is open. But there may be some function they may have used that we did not anticipate so it is possible it won't work.

      We've always recommended to update the RPT files to the current version being used, simply to verify they still work and then you don't run into upgrade issue like this.

      Thank you again
