The installer download fails with a "Tag mismatch!" error. It has happen on each download attemp. Failures occured at 20%, 7% and 6% of complete (100%) of download. I de-activated my Anti-Virus software after the first installation failure.

Seems like a network problem rather than a MATLAB problem. Keep trying, perhaps at a less busy time of day or night.

This might be due to the connection issue. The workaround that we are proposing is to restart your machine. I have heard that this issue is known and the concerned parties may be investigating further.
