Remote registry change

Hello,

I am trying to modify the following key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
"SourcePath"="C:\I386"

using a batch file with the reg import command to call a .reg file if I launch the batch file in a command prompt I get a command sucsessful but no changes were made if I double click on the reg file and click on yes the changes are made. Your help is greatly appreciated
