teechart.dll Registration Error ...

Hello,

I am having problems installing applications that have the tChart version 2.0.2652.22325. Specifically, when I install the application using Install Shield, I receive an error that the teechart.dll did not register properly. When I try to run the application, I get an error from the Microsoft error report generation tool as follows:

EventType : clr20r3 P1 : fevr.exe P2 : 1.6.2670.33500 P3 : 462e9488
P4 : teechart P5 : 2.0.2652.22325 P6 : 4616596f P7 : 12b1
P8 : 41 P9 : system.nullreferenceexception

The only way that I have been able to get our application that uses the tChart version 2.0.2652.22325 dll, is to use the Steema registration utility on the target machine.

We also have applications that get installed on the same target machine, but were created with the tChart version 2.0.2179.21172 dll. These applications install and operate correctly.

This is the first time that we have encountered this type of issue, and it has occured since we upgraded to the tChart version 2.0.2652.22325 dll. Do you have any advice?

Thanks,
Mark

Hi Mark,

If running TeeRegister tool on those machines solves the problem then it's most likely to be a licensing issue.

Could you please read this thread? It's about somebody who also found a similar issue. Try following Marc's suggestion on how to check if the license is properly compiled in your application.

Thanks in advance.

Narcis,

Thank you for the quick reply - THIS IS WHAT MAKES STEEMA!

I have read the tutorial and will try. Indeed, the tChart component is in a DLL that is being called by a main EXE. This main EXE does not have the license file, so my guess is that this is what is causing the problem. If this does not solve the problem, I will post back to this forum.

Thanks again for your help.
