Win7 Integartion issue

[Bharti, Brijender]

Hi,
I was using SVN on WinXP and migrated to Win7 64bit. I downloaded SVN 64bit 
(earlier was 32bit) 1.6.11. It gets installed but it does not get integrated 
with Windows Explorer. I can not see Tortoise SVN also in Program Menu. I can 
see it is installed in control panel and Program Folder.
I really appreciate any help to resolve this issue. I have tried uninstalling 
and installing 32bit version also but did not change anything.
-regards,
Brijender
