If you had got your PowerShot A530 unit without any S5300 S5400 driver CD or the latter is lost, you may choose to follow the links below. Without a special PowerShot A530 driver to your unit, you won’t be able to use all its Sceptre functionality. The basic S5300 S5400 driver from Windows is only able to support the minimum Power S285 set thereof. You are really in need of a fully-featured authentic S5300 S5400 driver.
For PowerShot A530 download, please just follow the IP43 R190 link.
