I have a complete fresh Laptop, installed with Windows XP SP3.

Each time I have enabled in it any of my two WLan Adapters I get the below error when I start Chanalizer 4. I upgraded to the last version in the web with the same result.

The laptop is a Dell latitude D830 and the WLAN adapters I have tried are

WLAN miniport adapter Broadcom 1505 Version 5.60.18.9
Cisco Aironet WLAN Cardbus adapter v4.4

I don't installed any utility for the adapters, I installed the .sys manually through the native XP hardware device manager, and both adapters work correctly.

If i disable the WLAN adapters, The Chanalyzer 4 runs correctly

** Please provide a brief description of what was happening immediately prior to this error **[Description]
