Dynamic PDF Crashing Older PC's

[rhetorikal]

I've created a dynamic pdf that I've tested on several machines and works well. However this pdf also needs to work on company computers that are fairly old, we're talking 40gb hard drive and original windows XP old here. On these old computers the dynamic pdf crashed adobe reader 9 where the static pdf form didn't. Sadly the form needs to be dynamic in order to work properly.

Does anyone have any ideas on how to make these old computers not freak out when they try to open the pdf? At the moment they can't at all and often encounter runtime errors or just crash completely. I was looking into converting it back into  static pdf or somehow flattening it at a final point.

thanks for the help.

I might be a memory management problem.

Acrobat Reader doesn't manage memory very well (if at all). If it needs, it tries to allocat memory, if there's no memory left, it crashes.

A quick memory occupation test (just opening your form) turned out this way:

- Reader 9.1 (no pdf opened) - 26.892K

- Reader 9.1 + your form (dynamic) - 335.380K

- Reader 9.1 + your form (static) - 53.232K

Your form, if dynamic, hogs almost 280MB more memory than the same form saved as static. Maybe your form just needs more resources than the older PC's have.

This is my 2cents, but this is a department i'm not very comfortable, maybe some of the forum users that are more knowledgeable of the inner working of Acrobat Reader can provide a better overview.
