[TYPO3-english] unable to reset install tool login password - 6.2

[Brandon Walsh]

Hello,

I am attempting to duplicate an install of TYPO3 6.2 to create a development version for testing changes to the website. I now need to log in to the install tool, but do not know the existing password (set by previous admin). So, I am following the instructions listed on the install tool login page:

"If you don't know the current password, you can set a new one by setting the value of $GLOBALS['TYPO3_CONF_VARS']['BE']['installToolPassword'] in typo3conf/LocalConfiguration.php to the hash value of the password you desire, which will be shown if you enter the desired password in this form and submit it."

I have tried this several times. The problem seems to be that the login page gives me a different hash each time I enter the same password. By the time I've put the hash into LocalConfiguration.php and tried again, the hash has changed. What am I doing wrong here?
