It’s what I have done : uninstalled all previous RW apps (5,6) and 7.
Installed a new file of RW7 and… this new installation found my previous stacks and themes from a RW6 folder which was supposed deleted… ??
Yes, I ran into this. It’s not too difficult to solve. My suggestion:
(perhaps re-perform the clean install of RW 7, having previously deleted all traces except the download .dmg of RW itself and your RW 6 Addons - as here.)
let the new install copy those Addons to where it wants
finally, when you’ve restarted RW 7 and tested that everything is working properly, delete (or perhaps more wisely zip and ‘hide’) any Addons that RW 7puts in other folders itself.
It’s looking more and more as though some difficulties reported here are due to previous installations. Strongly suggest deleting or archiving everything - but, again, once you’re satisfied that RW 7 is working perfectly.
