SVNSCC registration

Hi,

i'm using Vista x64 as operating system and have troubles registering the
latest SVN SCC plugin (1.6.6 rc0 - i also tried 1.6.3.1 both 32 bit). The
registration process seems to work normal, i'm using automated registration
with the correct e-mail adress and password, etc. At the end of the
registration process the dialog shows "Thank for registration ..." but when
i close the dialog it immetiately shows again and the registration process
starts again. Is this a known problem with the 32 bit plugin under 64 bit
(especially in Vista) operating systems? May be this has something to do
with the "Wow6432Node" registry key that is used for 32 bit applications in
64 bit OS.

I also installed the 1.6.6 rc0 64 bit version and registered it with
success. But the probleme with this version is that i can not select the
plugin as source control provider in VS2008 (and VS2010 RC). This seems to
be related to the ticket with subject "SVNSCC x64 not showing up in Visual
Studio 2008 on Windows 7 x64 RTM" (sorry i did not find any ticket number,
so i used the subject to identify the ticket).

Do you have any suggestions what to do to get the 32 bit plugin to register
or to get the 64 bit plugin to work??

Thanks in advance
Martin
