We had the trial version of AVG File Server Edition and it expired before we purchased a key.  I have tried unsuccessfully to reinstall the program (and key) as I get the following error (which I have seen many others have had) and cannot get it installed.

Description: General error (0x0659)
Error code: 0xC0070659

I followed all the instructions (AVG Removal Tool, Control Panel (was not there)) but still get the error. The key is correct as I get SUCCESS when I enter it in the beginning of the install.

Please let me know if you can help with this.
