x-fi drivers

I cannod add x-fi drivers to whitelist in defence
Two files : C:\WINDOWS\system32\Ctxfihlp.exe , CTxfiReg.exe - i click to “add to trusted apps” and nothing happening. i still have in logs “added to sandbox, partialy limites” everyday

cis 5.4 , xp 64-bit, Sound Blaster X-Fi Titanium pcie XFTI_PCDRV_LB_2_17_0008.exe 07.2010

Does any of the workarounds in App. is not working correctly, but does not seem to be s/boxed. What to do? [v5] bring a solution here?
