Helo HomerJ,
As of ALM12.xx the functionality has been removed. the alternative is the more powerful and better formatted Business Views for Excel. However if you wish to use the legacy way of generating reports the do the following:
1) Log into SIte Admin
2) Select the Site Configuration tab
3) Select the add new parameter button and a pop up box appears
4) Enter the parameter: ENABLE_CREATE_LEGACY_EXCEL_REPORT in the parameter name box and the value Y in the vallue box and accept the paramter.
5) Verify parameter is in the listing (it is dynamic and doesn't require a restart of the services).
6) Log into a project and test that the functionality is restored.

I hope this helps with your issue?

Thanks,
Dan
