The reason why the perspective tool cannot run in Windows 7 is that Windows 7 lacks a 64-bit system file than Windows XP and the 32-bit Windows 7 system solution is different.
First download the uploaded attachment, which contains the missing ddl file. Open the windows folder on drive C and check whether there is a "SysWOW64" folder. This folder is available only for 64-bit systems. Ghost, win + R is just the shortcut key), enter: regsvr32 c: \ windows \ syswow64 \ dx8vb. dll, and then click Run. Then run the View tool. Ghost, win + R is just the shortcut key), enter: regsvr32 c: \ windows \ system32 \ dx8vb. dll, and then click Run. Then run the View tool. Note: If a 64-bit system uses a 32-bit system, it is useless. In addition, you only need to put "dx8vb. ddl" in the corresponding folder, instead of registering it in the next step, the Angle View tool still cannot be used, and opening it will be suspended. This is because you copied it, but it is not registered to the system and the system will not use it, so you need to register it. There are many solutions for the 32-bit Windows 7 system on the Internet, but it seems that there is no 64-bit solution, which is hereby released.
