Installing Zotero 4 alongside Zotero 5?
Is there a way to install Zotero 5 on Windows 10 without it automatically removing the old Zotero 4 version? I seem to recall there was a parameter from the command line that would allow this, but I can't find it. And of course, I'd run the two versions from different program folders, with different data folders as well. And I would not sync the 4.0 version - I just want to use it to running a plugin (Papermachines) that no longer works in 5.0 - by exporting the collections I want to textmine with the rdf translator from Zotero 5 and re-importing them in 4. Would there be any problems with the Windows registry or any other issues that I should be aware of? Thanks!

That won't update any registry keys, so you might get some weirdness with file associations (files opening in 4 instead of 5, for example), but mostly shouldn't be a problem.
