The memory could not be "read"

I am getting the following error message:

"The instruction at "0x771ef715" referenced memory at "0x909090a0".
The memory could not be "read".".

My app is written in VB 6.0 using version 10.0 of Crystal Reports. I
use the Crystal Report Viewer 10.0 control on an Activex EXE to preview the
crystal reports.

In the scenario where I preview more than 2 reports,
I am presented with the error.

If I preview the reports one by one I do not get the error.

Has anyone had any similar problems?

I'm unable reproduce the error on my development machine, it only
occurs on the test machine.

Any help or suggestions would be great! Thanks"The instruction at "0x771ef715" referenced memory at "0x909090a0". The memory could not be "read".".

Welcome to the forums. :wave:

If everything is working fine on the development machine but not on the test machine, then I would look at the test machine itself, not my report.

When was the last time this test machine was defragged?

Did you do a formal install of your app on the test machine, or just copy files over?

Have you tried running the app on a machine other than the development machine or the test machine?
