这是我的代码:我的问题是只有.NET4.5存在才会安装.
但无论是否存在,都会安装MATLAB的MCR.
你能告诉我我的病情有什么问题吗:

 InstallCondition="(NOT MatlabPath) AND (NOT MatlabMCRPath)"

Rob回答后修复:

DetectCondition="MatlabMCRPathExists OR MatlabPathExists"

这种情况应该是假的,以便安装

Answer 1

这是我的最终和正在运行的代码:
此代码检查用于.NET 4.5安装.适用于Matlab R2012a或Matlab MCR R2012a.

Answer 2

该InstallCondition属性用于确定是否应在计算机上安装软件包。如果为 true，则允许安装该软件包。如果为 false，则卸载该包。您需要一个DetectCondition属性来确定该包是否已存在于计算机上。

解决方法可能只是将 Matlab 更改ExePackage/@InstallCondition为ExePackage/@DetectCondition.
