Unable to run in Windows 7 Ultimate

Hi, I need to convert the .wav files from court reporter to a standard format, (something playable in mac or linux). I have borrowed a computer running Windows 7 Ultimate, and attempted to install  Player562Setup.exe but it complains it needs .NET 4.0 Client Web.

I believe this Windows 7 Ultimate includes .NET 3.5.

Which FTR software version will work with this computer as is?

Thank you.
