AirPort Utility says a later version is installed & won't install
I don't have AirPort Utility installed on my HP laptop running Windows 7 Home Premium. It worked fine until about 4 months ago when it just stopped working. I uninstalled APU and have never been able to install it again. When it began returning with the message that a later version was installed (although what I was trying to install WAS the latest version), I began uninstalling Apple products trying to find where the computer was getting the information that a version of APU was installed. I've deleted common files under Apple, but the only occurrence of AirPort Utility is the install file I downloaded.
In the meantime, I have a Time Capsule, 2nd gen., that I can't access at all. Irreplaceable photos and photos of my artwork from 20 years ago - all on the drive. The network cable connecting it to the router is good, because I've swapped it out. When I plug the TC in, I get one green light flash on the front, and then the light flashes amber - not fast; it's slow & steady. I've tried connecting it to my laptop with the network cable. Nothing. I've connected it to my laptop with a USB cable. Nothing. I've been told I don't need the AirPort Utility to access the Time Capsule, but I haven't been able to find a solution without it.
