What compiler version?

If you're on Windows, and using a version of MSVC later than 6.0, have
you recompiled the adns library?  setup removes the old one.

I am using VC2005 (not the express edition).
No, I have not compiled the adns library myself, should I have to do that? I thought it was precompiled. The adns_dll.dll version I run Wireshark against (a copy of adns_dll.dll resides in \Wireshark\wireshark-gtk2 for instance, copied from \wireshark-win32-libs\adns- 1.0-win32-05\adns_win32\lib) is ver 1.0.0.5 from Oct 13, 2005 (this is adns-1.0-win32-05 if I understand things correctly).
