I have an application that uses com to open excel and access. The users may have different vesions of Excel 5.0 or 8.0 and different versions of access 2.0, 95, or 97.<br><br>For the Excel Spreadsheets The problem I am having is that I cant include both the 5.0 and 8.0 OLB.So if a user has a version different than the OLB I have include the cant use the application.<br><br>For the access databases the problem is that they are written in 2.0 and some of the users will have versions greater than this and may not understand they cannot open them with out converting them. <br><br>I know that I can get the data through ADO but that is not what they want. They wnat the apps to be opened .<br><br>Does anyone know how I can do this.
