I recently attempted to upgrade from 3.6.20 to 3.6.34 to get more profiles and opportunities to print more filaments with my Taz Workhorse and Taz Pro. I followed the steps to clean out the cache from %appdata% and %localappdata%, and restarted the machine. After installation, when I attempt to run CuraLE, it says it cannot find the executable. I am running Windows 10.
If you don’t have the option to continue (I know you used to) it may be your antivirus software. See this thread for the work around if you’re using McAfee
