Reg导入在批处理脚本中不起作用

Question

I'm trying to figure out why my reg import command is not working in the script below. When I run the reg import fileName.reg from the DOS it works fine but when included in the script below it does nothing and I cannot find why. I can see the export completed correctly and the format looks ok to me. When I use the the reg import command on the same exported file it works fine. Below is the code.

Thx......

@echo off
SETLOCAL ENABLEEXTENSIONS
SETLOCAL DISABLEDELAYEDEXPANSION

You need to 'escape' all backslashes in your *.reg script, eg (notice the '\\\\'):

[HKEY_CURRENT_USER\Environment]
"LIB_DIR"="C:\\Libraries"

Otherwise it will not work and you will have absolutely no idea why (no errors, warnings just nothing happens). I had this problem some time ago.

I hope that helps.
