Is it possible to run ryujinx canary on an administrator account on windows?

You don't always need to make a local account, or redownload each and everything. Try running Ryujinx as administrator, reinstalling the necessary dependencies, or testing whether your Anti Virus blocked anything, or moving the extracted folder to a more convenient directory (e.g. Desktop or C:\Ryujinx). You can also try deleting the config/cache files and reopening it. What error do you receive if it doesn't launch?
