We have a forms program created as an .xltm file stored on a shared mapped drive. Users have Windows 7 and MS Office 2007 installed on their workstations. When clicking on this .xltm document, Excel automatically opens and shows the right path to where the file is stored; however there is a message popup "The file could not be opened as Excel detected it as bring corrupt". On other workstations with the same configurations it seems to work just fine and once the macros are deactivated the program opens. This has become a problem as all new installations are running into this problem. Any help would be appreciated.
