how to install elements 6 on a new computer

There are no download links. Older software may not be compatible with a new computer. PSE6 was designed for

Windows:

Microsoft Windows XP with Service Pack 2 or Windows Vista

Mac:

PowerPC G4 or G5 or multicore Intel processor

Mac OS X v10.4.8 through 10.5.2

A new computer would definitely benefit from modern software. Why not download PSE 2019 and try free for 30 days. The interface is slightly different but most of the tools in Expert mode will be familiar with PSE6. Go here:
