Interesting as it captured the file twice and moved it to the VAULT at my request. It exists!
However, I misidentified the file as "aida_dll.dll". It is "aida_zipdll.dll"
I am looking at the contents of : "aida64extreme_build_2036_mxyv0c7zkw.zip" I downloaded on July 11 and when I look into the zip file, I see "aida_zipdll.dll Application Extension 7/10/2012 6:15pm 83,856"
So that DLL is in the ZIP package which I downloaded from your site. I can E-mail the ZIP or anything else to you if needed.
By the way, I let AVG remove that file (now in the vault) and AIDA works just fine.
