I can not open the downloaded file I bought license from Costco
I believe Costco only sells the desktop version. Are you using Windows or Mac computer? Does the installation file you downloaded end in *.exe (Windows) or *.dmg (Mac)?
Are you saying that you cannot install the program? What happens when you click the downloaded installation file to install the program?
