Hello

I am new with DNN and I try to install the newest version.
My system: WindowsXP / IIS 5.1 / MSDE 8

When I start the installation I get the message:

---------------------
 Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Line 20:         var nextButtonID = 'wizInstall_StepNavigationTemplateContainerID_StepNextButton';

Who can tell me, what's wrong here?

Thanks
