Unable to Set the Correct $_ADOdbPath

[developer]

Hi

I downloaded and am trying to install v3.2.0. Ran through check.php and all paths are "Ok", except for settings->_ADOdbPath. See below for the full result :

LetoDMS 3.0.0 check configuration (check version : 3.00-06)

Apache information not accessible

Check PHP configuration

PHP version: 5.2.14
gd2 : Ok
mbstring : Ok

settings->_coreDir : Ok

settings->_ADOdbPath : Error

Current value : letodms/adodb5/
Suggestion value : PLEASE INSTALL ADOdb

I have already uploaded adodb5 (in letodms folder), but it seems to be unable to find the path. I've tried all paths below, but to no avail :
/home/my_website/public_html/letodms/adodb5/
home/my_website/public_html/letodms/adodb5/
letodms/adodb5/
adodb5/
/adodb5/

Please help. Thanks.
