Installation: ADODB Error

[jbkirby]

I'm getting the following error upon clicking the apply button during installation.
ADOdb Path : Not found
=> Current value : C:/Program Files (x86)/Apache Software Foundation/Apache2.2/htdocs/letoDMS-3.3.0/
=> Install ADOdb

I downloaded the file ADODB515.tar and untarred it in C:/Program Files (x86)/Apache Software Foundation/Apache2.2/htdocs/letoDMS-3.3.0/

so I have the folder now C:/Program Files (x86)/Apache Software Foundation/Apache2.2/htdocs/letoDMS-3.3.0/ADODB5

Please help me. Thanks!
