Dear All,

I am using Adobe SDK to develop .api. Using sample code - basicplugin project. It can be built successfully. I put .api into adobe plugins directory. Reopen Acrobat and it can show menu. But it will show “invalid plugin detected. Adobe Reader will quit". I don't know if it needs to be enable by using tools Makekeys and singpluing to enable .api.
