Physics Illustrator – Tablet PC – uphill climb

Intrigued by the title I was as here was some free software from Microsoft’s Download Centre.
First attempt to install – “Sorry, this only works on a Tablet PC”
Second attempt to install, this time on a Tablet PC – “Sorry, you need Net Framework installed first”.
There was no third attempt. Physics cannot be this hard but if you’re using this software, please click below, tell us how useful it is and we’ll give it the extra effort required.
