labview无法加载MIFSystemUtility DLL

找了好久，在官网看到解决办法...

问题原因：

        This error could have different root causes depending on what software you have installed (or uninstalled) previously. If you have previously uninstalled NI software, this error can be caused by corruption in the unintstall process, failing to remove the appropriate registry keys. This does not cause any problems until software must be reinstalled and certain registry values are not set as expected.

        此错误可能有不同的根本原因，这取决于您以前安装(或卸载)的软件。如果您之前已经卸载了NI软件，则此错误可能是由于卸载过程中的损坏导致的，未能删除适当的注册表项。这不会导致任何问题，直到必须重新安装软件并且某些注册表值没有按预期设置。

简单一句话，之前安装过的注册表值有问题，需要删除，才可重新安装

解决办法：

To solve this error, you must manually delete the MIFSystemUtility registry key.

After deleting the registry key, you should be able to install the software without error.

删除后，秒解决...
