Install Prestashop v1.0 final error

[tnfsmith]

Hi all,
I try to install prestashop on localhost successfully. But the same source code I try on Host Windows (HELM panel) the error below:

Fatal error: Undefined class name 'tools' in C:\Websites\9vnd.com\wwwroot\prestashop\config\config.inc.php on line 31
PHP Fatal error: Undefined class name 'tools' in C:\Websites\9vnd.com\wwwroot\prestashop\config\config.inc.php on line 31

I can't run install on this host. If that it display as blank page (link sample http://9vnd.com/prestashop/install). Althought the range folders already exits and true the names.

How I solve this problems. Pls help me!!

Tools::redirect('install', $dir); <--- This is what i found in config.inc.php is it the same in your document??
Another person also had this issue the other day although i dont know if they came to a solution. Did you use an original install? or are you trying to copy your local install over???
I would go to your classes folder and make sure you have tools.php

I install by original method. I don't copy installation successfully on localhost over to Windows HOST. I make sure with you that I upload all files and folders root (download from prestashop.com). I install the same original methods on localhost and HOST but it successes on localhost, on HOST error above as you see.

Who see this error and fixed it? Please tell me why?
