error runtime

Hi support,
I developed applications with Visual Studio 2010 which I distributed with CRforVS_redist_install_32bit_13_0_22 and all ok.

Now I have installed Visua Studio pro 2019 on W10 and the extension for Crystal Report.
I updated one of my projects dll to the new version replacing dll reference.

I tried the project that uses Crystal, but I get error:
Error file "xxxxxxx" {"...xxxx ID xxxx ..."}.rpt:
Could not load database information.

What should I do?
I am in the situation that I can no longer update my apps to customers otherwise everything freezes (since they have the previous version of runtime).

I ask for support
thanks

A.
