Customers will sometimes ask you to support InDesign ME or InDesign CE. These are products created by Winsoft. Since these are licensed versions, it is difficult for us to obtain testing versions for developers.
InDesign 3 CE & ME as well as InCopy 3 CE & ME are built on an extended version of InDesign/InCopy. The extension makes it necessary to have a different SDK from the standard Adobe SDK. WinSoft does not provide a different SDK, but instead provides an “SDK supplement” that allows a developer to adapt his plug-in to the CE & ME versions.
