Alex,
In addition to Fiona answer ...
Under Win 7, to avoid problem we recommend to use the last version which is CW for HC12 v5.1.
The key question is do you want to move your V4.7 project to V5.1 ?
If you want to move your project on HC12 v5.1 which is the last version you can check in your Freescale account your condition to use the V5.1.
I recommend you to check in your account if the V5.1 license file is available and try to download it.
If you prefer to keep the V4.7, is it possible to use it under Win 7 OS ?
The tool HC12 v4.7 can not be installed under Win 7 OS (64 bit).
However you can install it under XP and copy the installation folder under your Win 7 PC.
Execute the \bin\regserver.bat file before to launch the IDE.
This should work.
Problem with P&E drivers.
You need to install new driver and refer to the FAQs provided by P&E.
Please have a look to P&E Microcomputer Systems - USB Multilink Universal - USB Multilink Universal All-In-One Development...
Click on FAQs, Manuals & Downloads Tab to access the FAQs and other information regarding the Multilink interface.
I recommend to check the FAQs:
FAQ_211 P&E Microcomputer Systems
FAQ_29 P&E Microcomputer Systems
At the end you should be able to use the tool.
Have a great day,
Pascal
