I have a VB6 application which pops up on the context menu of a E-Document. This works correctly on a 32-bit OS (i.e. on right mouse click of a text file, the application is displayed for selection). On 64-bit Windows 7, it does't show there.
This application uses APIs for adding the option to the Windows Registry and for displaying the same in the Context Menu option. Please let me know, if anything further is required to make this show in the 64-bit version of the OS.
