ExecutionEngineException using AxSHDocVw.AxWebBrowser

[sagar.jawale]

Hi,

In my c# windows application, i am using AxSHDocVw.AxWebBrowser.
I am displaying a generated receipt html in this browser. Also,
for printing the same html, i am using the following command :

axWebBrowser2.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT,
SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER,ref empty,ref
empty);

This works fine and Html is printed properly on some machines.
But on some machines, it is giving ExecutionEngineException or
sometimes
it is giving StackOverflowExceptions. Since as per the microsoft site,

we cannot catch these both types of exceptions at all.
Also, i cannot debug the occured exception, because it is occuring
only on client machines.

Can anyone pls help me to solve this problem?

Thanks & Regards,
Sagaraj
