Foo_run environment variable

see e.g. this thread:

foo_run + mp3tag

first i don't know if it's a mp3tag or foo_run bug, but i put foo_run to open mp3tag and it doesn't open, it work with other programs, only mp3tag doesn't open... thanks. edit: forget to say, in windows 7 home premium 32bits it work perfectly, but in windows 7 ultimate 64bits this problem happens.
