I have been creating a number of forms with Access 2010 and changing the extension from .accdb to .accdr so other in my office can use the form on the runtime version of access. This has been working fine, when the icon is double clicked it opens to the form. However, on the last two I made today, double clicking on the icon opens the Access runtime version but will not open the form.


Is there some setting I may have inadvertently changed?
Any input is appreciated.
