Arabic text in Flash

I have problem with arabic text in Flash. I read an external UTF-8 textfile into flash using #include. When I publish it looks as it should. When I view from other computers it all gets backward. It seems like RTL works on my computer but not on others. Why is that?

There is one thing though: on my computer I have arabic installed and not on the other computers. So I installed arabic on another computer and it worked. Do arabic need to be installed on the local computer for flash to show properly? If so, it´s kinda strange. For example html do not need that.

I would appreciate if someone could answer my question if arabic have to be installed or if there is another way for flash to show arabic.

Many thanks
