Installing Another App Using Wine?

[kalpana]

For apps that need Wine, every guide and tutorial I see never mentions anything about "If you already have Wine installed".

Those that do, tell to uninstall Wine and everything about it and update then reinstall what all you had.

I installed Wine-(staging) then installed a windows .exe app.

How can I install another app under Wine without uninstalling and reinstalling Wine?
