How can I get the value of a registry key from within a batch script?

Question

I need to use a REG QUERY command to view the value of a key and set the result into a variable with this command:

FOR /F \"tokens=2* delims=    \" %%A IN (\         


        

Answer 1

@echo off
setlocal ENABLEEXTENSIONS
set KEY_NAME=HKLM\SOFTWARE\Wow6432Node\Acme Software Inc\Common
set VALUE_NAME=InstallDir

FOR /F "tokens=2*" %%A IN ('REG.exe query "%KEY_NAME%" /v "%VALUE_NAME%"') DO (set pInstallDir=%%B)
echo %pInstallDir%

That works for me in Win7 where the key has a space and the value also has a space. So saving the above in c:\temp as test.bat, open a cmd window and run it.

C:\temp>test

C:\Program Files (x86)\acme Software Inc\APP\
