I will just delete any leftover in the folder and download again the Quartus installation files and re-install again. It is just a simple installation flow by running the Quartus installer.

Replies: Re: How completely uninstall Quartus and install a new fresh Quartus instead? yes, but there are still some leftovers in the registry, etc. after such kind of installation... So re-installing will not the same as installing the fresh version. Does Intel have some methodology for reinstalling the Quartus, which could give the same result as installing a new fresh Quartus version? Does Intel provide a tool for cleaning the PC from Quartus leftovers? Replies: Re: How completely uninstall Quartus and install a new fresh Quartus instead? Hi @amildm , Uninstalling on Windows* 1. Right-click on the Windows* Start menu and click Apps and Feature. 2. Point to <software name> <version number> > Uninstall <software name> <version number> . The installation wizard appears and guides you through the uninstallation process.
