"This software doesn't like Windows Vista and it's 64-bit operating system. CPAP.com warns about that, Respironics says on their website that it works on Vista. Not mine! I'd rate my computer skills at about average, and, in all fairness, will admit that some of my difficulty may have been caused by operator problems. I finally (after about 10 days)got it to install on an old computer running Windows XP. Hopefully the manufacturer will fix the incompatibility problem soon! Once I got it installed, the data is has been very usefull for tweeking my therapy. Good reports!"

"The software has many areas that need improvement. One big one is that you can't save the files to your PC and you can't copy them into Word or any text document. If you want to save the data, you need to print it off, or generate a new one every time you slip the card into the card reader.
It is interesting in that it shows how many apneas and hypopneas you have a night, and at what time (to the half hour). It doesn't tell you if you are having an obstructive or central apnea event."

"The EncoreViewer v1.0 Software and the associated Encore Smart Card Reader USB for the Respironics and REMstar CPAP machines are not compatible with any 64-bit Operating System, e.g. Windows XP, VISTA, or Windows 7. I contacted Respironics and they told me that they have no plans to offer a 64-bit compatible version of this product. I informed them that most Windows-based PCs sold today are 64-bit machines, and that without support for 64-bit OS's, their product is dead-end. They suggested I look for an older machine! This is not what I would have expected. I will say that their CPAP machine (M Series Pro) is, however, very good."
