I had that error with the 0.9.11 reported when I had an instance of 
Ethereal running that was already installed in the destination 
directory.  After exiting Ethereal (duh), it worked fine for me.  
Anything else that might have had wiretap.dll open may also have 
interfered with your installation.

I just downloaded 0.9.11 and in order to keep software I've installed 
separate from company-supplied applications, I attempted to install it 
into c:\Sam Sexton\Program Files\Ethereal. However, this failed as it 
claimed it was unable to open the first DLL for writing. I reran the 
installation into c:\Program Files and it worked fine. If this can be 
fixed, I'd appreciate getting a newer version, but I won't let this 
blight my life for the rest of the century!
 
Cheers,
