Im experiencing issues with compiling Nginx on Windows 7, every thing  
goes  
good until nmake -f objs/Makefile.  
I get the following error

Try to compile nginx without the rtmp first.

That’s an OpenSSL asm compile error, you need nasm [http://nasm.us](http://nasm.us)  
installed and in your PATH, masm which is included in visual studio is  
not supported by OpenSSL.

Nginx is not saving changing data when you try compiling. You may use Invalid data or code. So you need to check it or check [error 0x8024200b](https://babasupport.org/windows/windows-error-0x8024200b/) for window error code solutions.
