Hello PE,
There were download issues initially that Support found while trying to access the RU13 files. Please try again as this issue has been resolved for both GSS and the Support Tools installs, along with the other items that were updated August 22.
I used the HTTPS download link, and also selected the 4 files, and clicked "Download Selected" and used the HTTPS download option. Both are working now.
Please let us know if you're still seeing issues.
Thanks, Roy
