“ vsdfxavailable”的条件是什么意思？ （为什么我的自定义.NET设定失败？）

Question

在Visual Studio 2010中，我设置了一个项目“ Visual Studio Installer”，其中包括一个自定义操作。

在我的开发机器上，安装程序按预期工作。

在两台测试机（安装了.NET 4.0的Windows 7）上，安装失败。

该设置正在请求/尝试安装.NET 4.0框架（已经存在）。

使用msiexec installer.msi /l*v test.log我制作了下面的详细日志。

这使我相信我的问题与对发射条件的评估失败有关

vsdfxavailable

使用Google，我仅找到对粘贴日志文件的引用。

这种情况甚至是什么？有人可以查看日志文件并确认这会导致错误吗？

谢谢！

该属性似乎是由.NET框架启动条件使用的。尝试检查MSI中的Reglocator表，以查看启动条件是否使用Windows Installer搜索。如果确实如此，请检查计算机上的目标注册表条目是否存在。

另外，请确保.NET框架安装与您的软件包平台匹配。例如，32位安装程序很可能不会检测到64位.NET框架。
