I've been working in Premiere for decades, and in the process have upgraded both hardware and software. I've switched from PCs to Macs as part of those upgrades and am still running Premiere. I've been diligent about archiving my old project files. When I recently had to revisit a project I hadn't touched since 2007 when I was still using Windows, I discovered the Mac version of Premiere 2019 won't open the file. Adobe support was able to open the file on their Windows-based PCs, but there's no solution for me since I don't have Windows or PCs. I'd like to request that Adobe provide a very basic, bare-bones converter program that allows me to open these old files. I don't care if I have to re-establish all the new file paths since I'd have to do that anyway. If not built into the Mac version of Premiere, then please, at least make it a downloadable app from your support site.
