Hi, I had had a problem with my computer and had to uninstall Muse, now I tried to install it again but only found Muse 17.0.4, and I have my recent works in the 2018 version, and I cannot open them. I tried to update it, but it requires the Adobe Creative Cloud and don't appear listed there, is there any form to make an update without the CC?
can you please try to go on your CC app and then via preferences check the "Show Older Apps". After this try to find Muse in your apps tabs. I've post you some screenshot to help you with the paths to choose, its for Mac but it can be applied in a very similiar way for win.
Hope this solves.
