I am having USB scanner UMAX Astra 4500, i have tried installing Windows XP x86 driver v.2.6,vista x86 driver v2.6. as well as XP x86 driver but i am getting an error message saying "The INF file your selected does not support this method of installation". I have tried installing the driver using windows update but than i get another error message saying "Windows could not find driver software for you device.". If i point the updater to Astra4500.inf than it says "The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems." I am just running out of ideas now and i dont know what to try out further, Is there anyone who can help? Thanks in advance.
