Jahern,
The Installs are not counted against you. If you are installing on the Same computer.
Your problem is that the programs that you are removing also use a Wnaspint.dll file, as Microstudio does. These programs are then removing this file.
You could also fix this by downloading the Install just for the ASPI driver from:
