text: where can i download the file dao36.exe ? (data access object)? it´s from microsoft. the answer isn't likely what you'd want to hear.  from the first site listed below, it is apparent that the jet/dao components and applications are not supported fully any longer.  that leaves you with a couple of not so good options. first, do a file search on the internet and download a few copies.  make a survey of the file size and get a consensus so that you are fairly sure it isn't a tampered file.  virus scan it very thoroughly and then install it.  second option, find and purchase an older copy of a microsoft programming product that will have the redistributable included on the cd.  this will cost you and you should only use an obviously factory produced cd for the same reasons i advised the gyrations with the downloaded file from option one.  if you do get it and it is critical to your system, be sure and archive it in two or three places and keep the media safe, sound and separate.  the third option is to download the mdac 2.8 package and hope that it supports enough "deprecated" calls to work with your software.  i hope that this helps you out and wish you luck.
