windows 2000, about service pack i'm not sure..
menu document\security settings\windows id i pressed a button Add (+) (for creation new id in windows store) and appeared the error code 87. parametr is wrong.
but if create new id when i sign document (form "sign document" field "sign as" point "new id") its ok and i have got a new id in windows store...
Maybe some problem in Windows? because i have not such problem in XP
installation was made by administrator with full access on PC. creation was checked without full access on PC and with full access
i have already reinstall the reader. and check the same situation on another PC with windows 2000 the problem still the same
