Hi Xavier,
as explained Jennie we recommend to use XP OS for MCU V6.3.
This version was not tested under Win 7.
Now there is a problem since Microsoft decided to stop maintenance on XP.
We've already several customers using MCU v6.3 on Win 7.
The installer is not running but a customer found a way to disable the installer OS checking.
A video explaining the process has been posted too.
For more details, please have a look to:

Another solution is to install the tool on XP OS and to copy the installation folder on Win 7 OS.
I've used this solution on my side.
After you must execute the \bin\regserver.bat file.
Hope this will help you.
Have a great day,
Pascal
