Co-locating EV and SQL Reporting

Hi all,

For once, I need a solution :)

I looked through this guide on troubleshooting FSA reporting:

http://www.symantec.com/business/support/index?page=content&id=TECH51475

In the EV 9 & 10 document on page 28 it says:

<snip>

Note you cannot co-locate an Enterprise Vault server and the Microsoft SQL Server Reporting Services on a 64-bit computer

</snip>

My question is ... Why?

I have it on my EV 10.0.2 system, with SQL 2008.  And it works (apart from the style sheets being all broken, but that I suspect is my flakey installation, rather than reference to the comment above).

Hope someone can shed some light on it....
