Hopefully last silly question:-)
Do I need to uninstall the regular wallet or can this run on a machine along with the regular wallet?
I don't think there are two types of wallets. The latest versions now includes the xmixer tech. It should replace the current wallet you have installed.
1. Always backup your wallet.dat file to another folder before updating. The file can be found in username\AppData\Roaming\XCurrency.
2. Run the installer.exe.
3. To get xmixer tech running you need to append the Target line in the Shortcut tab. This can be found by right clicking on the shortcut to the program that was created by the installer on the desktop or start menu.
It should include the expression -distmix-autonode .
4. Run the wallet from the shortcut you just changed. You should now see in the wallet's title bar the addition of the word [autonode] which indicates the xmixer is running.
