I am writing a script the executes .exes and .bats automatically, eliminating any humna error...

I have run into a snag, can anyone help?

@ECHO OFF

:: START install
start /wait install.exe

set /p _setupdir=What was the directory you specified in the INSTALL program? EG "C:\Program Files\Civ3" Make sure to use "" marks:

cd %_setupdir%

IF EXIST setup.bat (

:: START decom
start %_setupdir%\setup.bat

) ELSE (

echo incorrect directory.
echo try again.
)

:: Stop
set _setupdir=

pause

basically I want it to work kinda like this:

{run install.exe}

{ask what the dir was in the install file, answer is saved in a variable}

{if setup.bat exists in the dir location, execute setup.bat in that dir}
{if not, re ask question (loop but I dont know how)}

{clear variables}

{pause}

like I said, can anyone help?
