Error opening program with Crystal Report. [Resolved]

[albertlse]

I had developed an Invoice System. This system uses Crystal Report to generate reports. Everything is working very fine. I also created an Installer for this Invoice System.

I used this
Installer to install Invoice System to a new PC. This new PC is empty. Only has Windows XP Home and Microsoft Access installed. Everything works fine. It can interacts with database file with no error. But when I try to generate report, error occurs. The error message is as below:

An unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will be shut down immediately.

Cannot find KeycodeV2.dll, or invalid keycode.

The details of this error message is as below:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

Why this error happens? How can I solve this problem? Do I need to install extra software to view Crystal-Report-generated reports?

Please guide thank you.
