How to check ac-3 codec install in my system

[A_51]

I try to use Cuttermaran for the first time. It sayd that I had no AC-3 codec installed on the system. By the way so does TDA. Even thow I just also installed AC3ACM.

I need some help to find out if there is no really a AC-3 codec installed on the system or if it just that the program doesn't see it.
This is the log from cuttermaran.

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.
