Airport for Windows doesn't start due to missing dnssd.dll?

I've just installed AirPort for Windows v5.4.2 on my Windows XP SP3 laptop, yet it doesn't start due to a supposedly missing dnssd.dll file.

The error message states: "This application has failed to start because dnssd.dll was not found. Re-installing the application may fix this problem" .

Re-installing does not fix this. Any ideas?

That's interesting. It's actually a BonJour dll, and it lives at:

C:\WINDOWS\system32\dnssd.dll

I can replicate your error message by dragging the dll out of system32 and on to the desktop prior to trying to launch the Airport utility.

If it has gone walkabout for you in a similar fashion, here's a way of getting it back.

Restart the PC. Now head into your Add or Remove Programs Control Panel. Select BonJour, click "Change" and then click "Repair".

Does the repair install of BonJour go through properly? If so, can you open the Airport utility without the error message?
