"Tahoma" font problem

hi everybody

i've written a project using VB and Access.

for VB control font property i have chosen "Tahoma" font, as i am using farsi (persian language) script. i have made executable and installable copy of the project.

in spite of the fact that when running the project in my own computer i face no problem and all captions appear in farsi script, doing the same (installing and running the project) in other computers, for some of the controls as command buttons or radio buttons, the fonts appear in some meaningless script, while for some others as labels the fonts appear properly and correctly.

amazing .... isn't it !!!

please help me in finding the solution ...

thnx a lot
