Visual Studios 2020 CR Viewer won't run in legacy programs

36 Views Last edit Sep 14, 2020 at 07:10 PM 3 rev

Since updating to SAP Crystal Reports version for Microsoft Visual Studio(13.0.28.3597), legacy reports created in .NET will not open unless the new version of the viewer is installed. Is there an older version of CR for Visual Studio that will allow the older reports to run without upgrading literally hundreds of reports and machines at the same time? Or is there code that can be inserted in the program to allow the older version to run? I have tried changing the app.config with <startup useLegacyV2RuntimeActivationPolicy="true"> Any other suggestions short of doing a mass company-wide change? I have reverted back to my old computer with the version that works for the installed programs for now.
