Problem after installation

I installed a software in my PC which uses MS-Windows 98 and when I tried to execute the program, the following error message appears:

Fatal Application Error
This Application has Unexpectedly Quit
Invocation of this Java Application has caused an Invocation TargetException. This application will now exit. (LAX)

When I press the button Details… the following messages appear:

at sp.Main.main(

at java.lang.reflect.Method.invoke(Unknown Source)
at com.zerog.lax.LAX.launch(DashoA8113)
at com.zerog.lax.LAX.main(DashoA8113)

Someone knows what this means? How can I solve this problem?
Thank you!

Dear Marcos,

Sorry for my late response. Can you tell me which software that you have installed?

Best regards,
