What do you mean by crashing?

Is Chanalyzer crashing or is a wi-fi driver crashing?

What is the error code?

Is there an associated entry in the event logs?

To see wi-fi networks you must have a wi-fi receiver.
I suggest that you buy a usb wi-fi adapter. They are very inexpensive.
Prices start at less than $10.

inSSIDer requires a wi-fi card to provide the data that it reports.
In other words inSSIDer talks to the wi-fi card and is not capable of receiving wi-fi signals directly.

What is the model of the wi-fi card in the machine where inSSIDer is installed?

Yes, your understanding is correct. inSSIDer reports the signal power measured by the client's wireless network interface card (NIC).

0 dB designates the top of the scale (highest possible level). Measurements expressed in terms of dB will be less than 0 dB, a negative number.

The overlapping designation applies only when an overlapping channel is in use.
Adjacent channels always overlap their neighbors.
The only channels that can be used concurrently without overlapping...

What dll is missing?
Are there errors or warnings in the event logs that may be applicable to the installation?

The new product inSSIDer for Office is bundled and works with the new Wi-Spy Mini.
Does inSSIDer for Office also work with the Wi-Spy DBx?

Try downloading a fresh file. The one you have may be corrupted and/or the path may not be accessible.

Wi-Spy does not require special drivers.
Windows automatically recognizes it as an HID.
Just plug it in and start Chanalyzer.
It does not need to be dismounted before disconnecting.

More info is needed.
What is the model # of your router?
Post an inSSIDer screen shot that shows the network.

Many dual band home routers from Linksys, Netgear, D-Link and others are capable of a 450 max rate. The theoretical max rate for 802.11n is 600 Mb/s.

By 2014 maximum theoretical data rates will...

There is nothing unusual there. What you are seeing is an SMC device, based on the first portion of the mac address - B89BC9. The other mac addresses are logical access points available on that...

See the link in my previous post.
With your low screen resolution, you'll need to stay with inSSIDer 2 until this issue is resolved.

For the client the channel width - 20 MHz or 40 MHz - is set in the adapter properties.
Channel bonding in the AP is set by using the administration app that is part of the AP.
It is usually...

That shows channel bonding of two 20 MHz data streams bonded to create a 40 MHz data stream.
It is part of the 802.11n spec - not 802.11g. The capability is enabled in the wifi router and/or access...
