register dll - GUIDs not found in registry

Question

i've got a c#-dll and registering via regasm tells me success, but the GUIDs have not been added to the registry and therefore, the component can't be used anywhere. and i've got simply no idea why :(

class attributes:

[ProgId( "blup" )]
[ClassInterface( ClassInterfaceType.None ), ComSourceInterfaces( typeof( blap ))]
[Guid( "0CFEF92B-A155-4353-B7A3-58A717193E0C" )]
[ComVisible( true )]
public class blup
...

interface attributes:

[Guid( "9FD1B3E5-4873-403a-91AA-2EEC7296B38D" )]
[InterfaceType( ComInterfaceType.InterfaceIsIDispatch )]
[ComVisible ( true )]
public interface blap
...

assemblyInfo.cs:

...
[assembly: ComVisible( true )]
[assembly: Guid("37639A04-9DAC-40ee-ADBB-2F07F78FD265")]
...

option to make assembly com-visible is set true. registering for com-interop ist set false, since i don't want it to be registered with every build.

registering via regasm /codebase -> success. registering via regasm /codebase /tlb -> success.

but in both cases, i can't find any of my GUIDs in the registry.

adding the /regfile param to regasm, the file is generated but only consists of there lines:

[HKEY_CLASSES_ROOT\Record\{D4DAB0A5-AC0A-3498-BD1E-6665735B5649}\1.3.3.7]
"Class"="<classname>+eventType"
"Assembly"="<name>, Version=1.3.3.7, Culture=neutral, PublicKeyToken=bba2258cd5ab986c"
"RuntimeVersion"="v2.0.50727"
"CodeBase"="file:///<filename>"

the GUID from the regfile isn't used anywhere in the vs-project. the whole thing is running - or rather not running - with visual studio 2008 on windows 7 64.

thanks for any hints in advance. if i've missed to give some informations, please let me know!

The problem is likely in the different view of the registry for 32-bit and 64-bit programs. Something like you register the .dll as a 64-bit server and then look with 32-bit regedit or vice versa.
