I have every html page and asset for my old Muse web page, but can not locate the Home page with app icon on computer, so can't open in Muse. Is this the end of the website I created?
Without a file with the ending "yourfile.muse" there´s no way for muse zo do anything, sorry. A html is not doing the job here.
Do you have a paid Creative Cloud All Apps plan? That's the only way you can access Muse because it's discontinued.
Is Muse installed on your computer? Check your Start menu or look in your Applications folder.
