Download error

When Installing Solisworks updates / service packs I get the following error..

Installation files could not be downloaded because: Internal Error: CoCreateInstance({652E77B7-69AA-491B-8C64-25B79239863F}) FAILED. If the problem persists, a proxy server might be preventing automatic downloads. Choose the option to download files manually instead.

To the best of my knowledge there are no firewall/antivirus/proxy issues.

Any ideas?
