License not valid after re-installation

License not valid after re-installation

Postby quimeraec » Tue 28 Sep 2010 13:27

I need help with the following error:

"License not valid due to dotConnect for MySQL Problems with installation" :?:

I have reinstalled "dotConnect" but did not succeed in solving the problem. :(
Also during the second reinstall I got the following error message on log file:
"Message:" Failed to retrieve a COM class factory for component with CLSID (31411198-A502-11D2-BBCA-00C04F8EC294) because the following error: 80040154.

My computer and software are:
Sony Vaio. I3 Intel Core 4MB RAM
Devart DotConnect for MySQL 5.80.152
Windows 7 x64
Visual Studio 2010 Ultimate.

Please try performing the following:
- uninstall dotConnect for MySQL;
- delete all Devart.* and policy.*.Devart.* files from the GAC;
- clear the Program Files\Devart\dotConnect and Program Files\Common Files\Devart\dotConnect folders;
- clear the bin and obj folders of your solution;
- re-install dotConnect for MySQL.

If the problem persists, please send us a compiled binary of the project in which it occurs so that we are able to investigate the issue in details.

As for the 'Failed to retrieve a COM class factory' error message, it specifies that the integration of our documentation into the Visual Studio help failed. This message can be ignored as this integration will be performed at the first launch of the Visual Studio help.

It worked after:

- uninstall dotConnect
- remove all references to Devart included in the Windows Registry.
- clear bin & obj folders
- make some adjustments to the solution or project (designer.vb & licx files)
- re-install dotConnect

Thanks a lot
