Problem with SAP CR 2020 on runtime-machine

[former_member768852]

I created a VB.NET.DLL (VS 2015) to start CR-Reports from a VB6 Programm.

Everything is fine on the development-machine.

But on the customers runtime-machine I receive automation-Error -2146233036.

I Installed the SAP CR runtime-Engine for .NET Framework 64 bit on the target-machine.

I also installed the CR Viewer.

Same result with automation Error.

I even get the same error, when I remove the CR-Report-Version from my develop-machine.

It seems, that my vb.net-DLL only runs, when CR-2020 ist fully installed.

What do I have to install on the target-machine??

I use a 30 Days test-license.

Has anyone any ideas?

Found! Here my solution:

After changing my DLL into a Windows-Form-Application, received this more detailed Error:

"CrystalDecisions.CrystalReports.Engine.ReportDocument" has thrown an exepiton.

This lead me to advices, that this Error indicates, that the runtime is not properly installed on the target machine.

Then I deinstalled the 64-runtime-engine and installed the 32-runtime-engine (despite of the machine is an 64-Bit-machine)

Result: Everything works fine!!!!!!!!!!!!!!!!!!!!!!!!!

Maybe this lines help someone to save hours and days
