The KB article refers to the problem occurring if you have v 7 of msvcrt.dll and msvcirt.dll. I have these as I also have XP SP2, but have not had the runtime error with EMC8 or anything else for that matter. So maybe that is not the right diagnosis for the particular runtime error you got. If you google for the error, you will find many other possibilities.
However, to get the patch, contact (phone) Microsoft customer services in your region; explain straight away that you need the patch referred to in that KB (quote the number), so that they will a) not charge you and

not refer you back to your PC vendor if it was an OEM install of XP. They will probably pass you on to technical services with a job number and technical servuices will then send you an email with a link for the download.
