MSComm control registration

I wrote a MSComm serial communication program and couldn't run it on a machine without VC installed. You need to manually register the control. For more information, see http://www.cnblogs.com/yrh284269/archive/2007/06/19/789213.html. However, manual registration can be completed by writing a BAT file. First, create a folder and set MSComm under Windows/system32. copy the SRG, mscomm32.ocx, and mscomm32.dep files to the folder, view the content of mscomm32.dep, add regedit4 lines to the top, save it as 1.reg, and put it in the folder.
Create a text in the folder and write
@ Echo off
Copy. \ mscomm32.ocx % SystemRoot % \ system32
Copy. \ mscomm32.dep % SystemRoot % \ system32
Copy. \ MSComm. SRG % SystemRoot % \ system32
Regsvr32/S % SystemRoot % \ system32 \ mscomm32.ocx
Regedit/s 1.reg
Save and change the suffix to bat. Click Run to complete registration.

There is another Win32 application method. I also want to learn it. However, it is easy and convenient to use the BAT file.
