Quotes and Orders Issue with SageCRM 7.3

Hi.

I'm wondering why this is happening.

When I add an opportunity and I click on either a quote or order I get the following error:

Errors When Opening Program
The portal cannot display the program you requested.

Just wondering, does this mean that I don't have the module installed? And if so, is there a way to re-run the option to install this module?

Let me know.

Thanks,

Stephane
