CAV License Activation Module error


I’m trying to install the CAV (I already have CF) on my laptop, but no way.
When finished the installation, and License Activation Module start I get this error:
AppName: softact.exe AppVer: ModName: mfc71.dll
ModVer: 7.10.3077.0 Offset: 000ad49c

I have tried in my office, behind a proxy, and at home, without.
Previuosly I had installed Symantec Norton Antivirus, and uninstalled correctly.
I have WinXP with IE7 english.
The mfc71.dll in the Comodo dir is the same size and date of the one in the windows\system32 one.
Do you have any suggestion?
