That is hard… 64bit hardware has taken over 10 years ago. Usually the limitation was that users wanted to run 64bit-only software but had 32bit hardware. But since a 64bit version of your operating system is easily available and can run on your hardware, have you seriously considered either replacing/reinstalling your OS, or installing the 64bit version in addition to it (“dual boot”)?
- Otherwise, use the web-based SketchUp Free (it is automatically updated and can open the latest SketchUp files)
- Or try to find an installer for SketchUp version 2016 or earlier (it doesn’t matter whether “Viewer” or “Make” which is easier to find). These can only open old SketchUp files (2016 or older). They are also so old that the installers are even not available anymore from the official download page, so be careful what you download!
