Got ComposerCloud. Downloaded their installer. Launched it. Now it shows just a menubar icon. It can not be clicked and the app does not show the installation window at all.
Anyone else that have had this problem?
Got it solved by EW support. Copy/paste here in case someone would search for a solution.
If you have user fonts you want to keep, Open your finder, hit Shift+Command+G and go to both
~/Library/Fonts (your user fonts)
and make a backup of those folders somewhere else.
2. Open the Fontbook from Applications > Font Book
3. In the top menu bar select File > Restore Standard Fonts
Then close that and the EW Installation Center should open.
