Chris,

As you have probably read in the other thread (TSU7500 en W8), I created a virtual environment with VMWare and from there that program I first installed a retail version of Windows XP, and from there I installed the Pronto NG software.
At a certain point in the installation procedure it was asking for the driver software (which where not in the directory I was using for installing). I directed it to the two files (which you have got) on my cd-rom and everything went well.

After that I could use the software and upload en download (to and from the TSU7500 and the RU990/9980) freely.
