I want to create a batch file or vbs. here is the thing I want to do 1)verify if a specific reg key is in the registry. 2)If it's there, exit 3)if not lauch a batch file Is it possible to do that? thanks for your help.

Yes, it is possible @Echo Off Reg Query <key-structure> If not ErrorLvel 1 GoTo :EOF NewBatch Where NewBatch is the batch to be launched and to set >key-structure> follow the help displayed typing Reg Query /?.

Hi IVO, When I type: Reg Query /? in w2k, I get the good old: 'reg' is not recognized as... ===================================== If at first you don't succeed, you're about average. M2

Salve M2, very strange as the line command Reg.exe is standard since Windows 2000 and many tools delivered in Win 2K lack in Win XP on the contrary. See the following link for more info http://www.robvanderwoude.com/index... and may be you like the site too. Any way the owner of the thread declares running under XP.

ok I create that: @Echo Off Reg Query <HKCU\Software\martin> If not ErrorLevel 1 GoTo :EOF 2.bat nothing append, I see the command windows open really quick an thats it

Well if the windows opened and closed in an eyes wide shut, the key you was looking for exists and the batch ended without launching 2.bat. To proof that slightly modify the batch Reg Query <HKCU\Software\martin> Echo.ErrorLevel=%ErrorLevel% Pause If not ErrorLevel 1 GoTo :EOF 2.bat If you get ErrorLevel=0 the GoTo :EOF statrment is executed and the batch terminated. I hope your system has the reg.exe command.

And avoid to embrace the key by <>. Did you see the /? Help, as I suggested?
