The error message states the above and advises to "Delete the source directory and then rerun the Installation Manager to download the files again."

I uninstalled Solidworks and re-ran the installation manager 3 times but continue to get the error.
I tried running Solidworks anyway after the 3rd attempt and getting the error. It opens but crashes each time after drawing a circle as instructed in the beginning tutorial.

Running Windows 10.
GEFORCE GTX1070 video card.

An Internet search on similar errors found that if the installation was going into a path that contained more than ~50 characters, the installation location needed to be to a shorter path.

Any ideas what to do?
