How can I deploy .Net applications that uses different version Crystal report on same machine

I have a few .net applications that use dll version 13.0.2000.0 from CRForVS_13_0_17 for VS 2015.

Lately we started to develop some applications using dll version 13.0.4000.0 from CRforVS13SP26_0_0 for VS2019. But majority of the applications are not ready to upgrade.

Users want to be able to run old versions and new versions of our software on same machine. They also want to install different applications with different crystal versions on the same machine. WE do not have control what users want to install and in which order. Any idea?

Is it ok to copy Crystal dlls and paste into application folder?

    There are instructions for how to do something like this in the Crystal for VS wiki. Look for "WinFormCRViewer.zip". There's a link to a KB article above it that explains how to use it.

    Only one version of the runtime is allowed on the same PC.

    Info Dell posted above has your answer.

    Uninstall the old version, install the new version and add the config file to do the redirect.
