Do you get an option to Retry the download?
See if you can get your SolidWorks reseller to get a DVD of the download.
Thanks for your answer.
I haven't got an option to retry the download. And also, same error with the DVD download. It failed at anywhere between 100 MB and 411 MB. It is really weird.
When I tried to download SWComposer(64-bit) (630 MB), it succeeded. But this is not the version I want. I just did a test to testify my computer and network has no problem.
There should be something wrong with the download server.
