全安装Office2010后打开InfoPath Designer的【CodeEditor】,弹出错误窗口显示“Object reference not set to an instance of an object”,关闭该窗口进入编辑状态,编译后出现错误“Error 1 Cryptographic failure while signing assembly 'C:\Users\rxtang\Documents\InfoPath Projects\Form43\obj\Release\Form4.dll'
-- 'Bad Version of provider. ' Form4”
重装Office2010后还是不能解决。
