[Inkscape-user] how to ID a 7z version from Inkscape window?

Hi Friends, Trying to help someone in a forum, I was trying to figure out whether the version of Inkscape which would open on double-clicking an SVG file had been installed via EXE installer, and which one wasn't technically installed, but was from an unpacked 7z download. I wanted to know which one was associated with SVG files. As far as I can tell, the About screens are identical. Is there some way to know which version you're using? I tried searching LP, but couldn't find some good search terms. So how to tell which 64-bit version version you have open, if you have both 64-bit exe installed and 7z onboard and unpacked?

Thank you very much, brynn
