The file F-MIT.msi cannot be found.. Asks you to browse to the file which be default it looks like its usually stored in some temp folder. We recently ran a cleanup of all temp files on this system but it was a couple weeks ago and ArcGIS has worked since then. Anyway - click on cancel on the error and get the following: Error 1706. No valid source could be found for product F-MIT. The windows installer cannot continue. Click on close or ok on this and you can go into the software and use it as normal. I looked for this file on the install CDs and could not find it and searched the entire C drive and it was not found. Any thougts?
