Call to undefined fuction lang() during upgrade

[happyhardik]

Hi,

I am trying to upgrade my opengoo, from version 1.3 to 1.5 and it says:
Fatal error: Call to undefined function lang() in html\time\public\upgrade\index.php on line 11

For your information, here are my environment details:
OS: Windows Server
Server: IIS 7
PHP: Version 5.2+
Database: MySQL 4.1+

Version 1.3 was working fine, I followed the instructions and left the config and upload folders and overwrite the other folders and than this happened.
Any help would be appreciated.

Thanks,
happyhardik

I do believe that Pet has his installed on a Windows Server.. maybe he can help out?

Also when you go through the install process, has it already altered your DB?  If so then maybe you could just save a backup of your DB (then empty it) and your upload folder, run a fresh install (and go through the admin set up process so that the config file can be written) and then restore your backup and upload folder?

I ended up having to do that in order to go from 1.4.2 to 1.5.3
