Invalid pointer exception after TeeChart upgrade

UserLS · Post by **UserLS** » Mon Jan 12, 2009 3:44 pm

We upgraded TeeChart from an earlier version to version 3.5.3274.30664. Now, when we compile from Visual Studio 2008, the projects containing TeeChart references fail as follows:

'Could not load file or assembly 'TeeChart' or one of its dependencies. Invalid pointer (Exception from HRESULT: 0x80004003 (E_POINTER))'

What do we do to resolve this? Nothing has been changed except TeeChart was upgraded.

Hi UserLS,

You could try removing your project's TeeChart reference and adding it again.

If this doesn't help please send us a simple example project we can run "as-is" to reproduce the problem here. You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi, I was able to get this resolved, but it was necessary to first uninstall your product. Then, I had to go through the registry deleting a large number of items that you added in the install for previous versions. Once I had done this and reinstalled the product, there were no problems.

It appears that your setup program fails to clean the registry of these old entries. This is particularly a problem regarding Visual Studio. I was able to build from a command-line MSBUILD, but could not build via Visual Studio. My guess is that the cause was the many Visual Studio registry keys you had pointing to your previous version.

No problem, but it would be nice if Steema could get this fixed.
