I have purchased and installed Parallels Desktop 20 on my MacBook Pro 16" 2019 back in May 2025. So far I have installed Windows 11 using the inbuilt options in Parallels. I have not activated Windows at this time. I have tried several times to install Parallels Toolbox after launching "Install Parallels Toolbox for Mac..." in the Parallels drop down menu. When I click on the "Install Now" button I get a short attempt to download the Toolbox, but the progress bar only gets to about 50-200KB out of 2.5MB download, then it quits back to the installation screen without having completed the installation. There are no error messages, and even after restarting Parallels I don't have the Toolbox icon in my Mac OS menu bar. Am I missing a step somewhere ? Do I need to activate Windows 11 before it will install the toolbox ? Mark C.
