DV2000 version 7 and above no longer use this method to determine what applications are running and therefore is not an issue.

DuVoice requires the ability to enumerate all process running on a system. If the system cannot start and or all your performance counters are numbers rather than text this will resolve the problem. This is a known issue in Windows 7 and all prior versions.

This problem can be verified by looking at the following registry path. If it's blank then this is in fact the issue. If this path contains the key //**Counter**// then verify 5.31.48 or 6.03.45 is installed.

<code>
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Perflib\009
</code>

===== Windows 7 =====
<code>
lodctr /R
</code>

If the above command doesn't restore the performance counters, download this [[https://downloads.duvoice.com/windows/win764bitcounters.zip|zip]] file for 64bit Windows or [[https://downloads.duvoice.com/windows/win732bitcounters.zip|zip]] for 32bit. Unzip the contents and double click on the **.reg** file within. This typically will resolve the issue.

**You will also need the latest release of the version you have typically to help resolve this issue.**.
