Error accessing registry value in report

We store environment specific information in the registry to ease moving from
dev, test and production environments. I'm making a call in the code window
to read from the registry and am getting this error:
Failed to load expression host assembly. Details: Request for the permission
of type System.Security.Permissions.RegistryPermission, mscorlib,
Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.
(rsProcessingError) Get Online Help
Just as a test I've changed all code access security zones to Full Trust but
this hasn't helped.
Please advise.This is what I had to do to get this working, if anyone's interested:
Edit C:\Program Files\Microsoft SQL Server\MSSQL\Reporting
Services\ReportServer\rssrvpolicy.config and modify the entry in the
Report_Expressions_Default_Permissions CodeGroup and change it from Execute
to FullTrust.

>|||Giving FullTrust to Report_Expressions_Default_Permissions totally opens
your server for hacker attacks. Now all expressions incliding VB.NET
snippets in Report.Code have fulltrust which allows them to perform any
operations, including formatting drives, reading and writing files etc...
The better way is to create a custom assembly with functions to read
registry and call this assembly from your reports. You will then give only
RegistryPermission to that assembly.
