Query: Software inoperative on either Windows Xp or 8

Ordered this version for the computer SW tracking feature. However, the SW cannot install on windows 8 (it only yields an error message) and my Windows XP machine cannot even recognize the disk (yes the drive is working).So, I'll have to return as defective. I like the device, but really wanted tracking function to use in conjunction with a Lung Training device because I have poor lung function. PS there is NO SW patch or drivers to download from the MicroLife website. They seem not to support this product.
