Using 2011 SP2.0 Installation Manager [X64 Edition] have tried a new installation of SW 2011 SP2.0.

Get message " The downloader could not be started due to an internal error. Try downloading manually."

Then select "Download files individually in web browser"

Over the last 2 days (and nights) I have downloaded the requested files numerous times into the directory users\xxxx\documents\solidworks downloads\solidworks 2011 x64 sp02.

When going back to IM and selecting "Next" it continues to tell me "Some manual downloads could not be verified or extracted. They may need to be downloaded again. Use the built-in Downloader or download the remaining files manually."

I have done this numerous times.  I have looked in explorer and all files appear to be in the download directory.

How do I get out of this endless loop?
