Ok first are you on enterprise or the home product. You appear are not in japan though you are posting in the japan corporate support area. At least your IP says you are not.
That said if it is home product you must have an account so go to www.mcafee.com and change to ypur country. Click on My account links and use the email and password you used to create the account. You can then download the program from there. If you are only running the MCPR removal tool deactivate the program for the PC you want to install it on.
That said 2 things to watch out for. If there even was a mcafee copy installed good to follow this to remove and bits and pieces
If there are no mcafee programs to uninstall in widows programs and files area (or add/remove) run the MCPR removal tool alone.
Of course if this is enterprise forget what I said above and I will move this to the correct forum whichever 1 is pertainent.
