I have a downloaded image of SP05 of 2013 to install on my offices computers, but it is trying to download an additional file that is coming up as unavailable. I tried manually downloading per its instructions and get the response "File not Found" from the download server. My company is still using 2013 due to some of our custom add-in software not working with newer versions and we are not in a place to re-write this software.
If it is any help, we are current on our license and I was able to download and install on a machine a few weeks ago. Has Dessault completely stopped supporting 2013?
