CR13 SP27 Runtime not support ​CR13 SP21 ???

[former_member698713]

Hello, I'm working on VS2019 and CR13 SP27. I installed my program on another computer and installed CR27 runtime, When I run My new program all is good and reports show without error.

But when I want to run my another program that I ever installed(My old program working on VS2017 and CR13 SP21 and installed CR21 runtime in client computer), it gives an error below:

System.IO.FileNotFoundException: Could not load file or assembly 'CrystalDecisions.Web, Version=13.0.3500.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The system cannot find the file specified.

I wonder CR13 SP27 Runtime not support CR13 SP21 runtime ?

Before I install SP27 runtime I uninstalled SP21 runtime Is it related?

How to make my all program work well with CR report difference version on another computer?

Please help to solve this problem.

Thanks in advanced.
