Although I know the guides about downloading product old versions, I cannot see the download link for old versions. I have a registered account but I think guides are too old.
I apologize that this was not addressed sooner. The article has not been updated to account for the current version of the Intel® Registration Center. The version and build dropdowns have been combined into a single version dropdown. Simply select the version you want from this dropdown.
Another thing to mention is that the community licensing does not enable the download of previous versions - only the current version. The Parallel Studio XE licenses do enable the older version downloads.
