TeeChart.NET V3 Licensing Problem on Windows 7 64Bit

[Michael Breu]

Hello,

We have a problem with licensing in Windows 7 64Bit.

We have developped since 4 years an application on VS 2005.

Now we have upgraded our development machines to Windows 7 64 Bit.

We reinstalled VS2005 without major problems.
However we get a licensing exception:

Sorry: this is a German localization, however the major error is: 'Steema.TeeChart.Chart, TeeChart, Version=3.5.3498.27367, Culture=neutral, PublicKeyToken=9c8126276c77bdb7' System.NullReferenceException during license creation.

I have retried various hints: Reinstallation of the TeeChart as Administrator, Looked on Tutorial 17, Installed 64Bit-Version of TeeChart, but nothing changed.

Any Idea what get's wrong?

Hello Michael,

This is probably that the design-time license is not properly installed on that machine. So, I recommend follow the steps you can find here to try to solve your problem. Moreover, When you want compile to 64-bits, you need specific assembly x64 that you can find in the Download Customer page.

If previous suggestion, doesn't solve your problem, please let me know.

I hope will helps.

Thanks,

Hello Sandra,

Thank you for your prompt reply:

This are my results:

1. Make sure that licenses.licx is built as an embedded resource in your project as told in tutorial 17.

That is the case.

2. Reset your machine's AssemblyFolders entry as told here.

There is no TeeChart specific entry in

HKEY_CURRENT_USER\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders

or

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders


3. Check if the NetDemo project shipped with the installation compiles fine at your end.

I found a DemoProject-Folder. It compiles with the same result: NullReferenceException during License generation.

4. Check if invalidating DesignKeyV3 on your machine, as Marc described here, makes any difference.

It makes a difference. If I invalidate the Key, I get a different Error message.

5. You could also use TeeRegister tool, available at the client area, to make sure the design time license is properly installed on your machine.

Ok this finally hits the spot. Now it is up and running.
Thank you for your kind support
