When VMware Server 1 is installed in win7, this problem will appear in two versions of VMware Server 2. The reason is that win7-64 bit system needs driver signature. If the driver is not signed, there is a problem with the installation of vmware server program. You can check whether the system services related to Vmware have been started, and those that have not been successfully installed are as follows.

The normal thing is this:

Normal login of vmware server is as follows:

The key to seeing the above is to have the localhost option. Do you know what to do? Disable driver signature enforcement in win7 and reinstall vmware server. Then the problem came again. How to disable driver signature enforcement in win7? Some netizens said that bcdedit.exe-set loadoptions _ integrity _ checks is enough. I tried, but it didn't work. My solution is: Every time you open win7, F8 enters and selects "Disable driver signature". Problem solved. (^_^)
