Installation Problem with Sneak Preview SP16

Question

Hi folks,
as I was trying to install Sneak Preview NW04 SP16 Full Java version, I am facing a prbolem as below.
As a first step to install, when I clicked the SAPinst.exe, I got a screen whenin it asked me to enter the host name and the TCP/IP port to log on, with the default host and port filled in as "localhost", "21212" respectively.  I accepted the above default values and clicked on the logon button.  Then, the next screen popped up with licence agreement, and once I clicked on "I agree" button, I got the following error and could not proceed further.
"An error occurred during the installation of component SAP NetWeaver Sneak Preview '04 Support Release 1 > Migration - Target System installation.  Press the log view button to get extended error information or press OK button to terminate the installation.  Log files are written to C:\PROGRA~1\SAPINS~1\MW04SR1\WEBAS_~1\ONE_HOST".
In the log browser, which popped up later, I have noted the following three warnings.
"Error 5 ( Access is denied), in execution of of a "RegOpenKeyEx" function, line (67), with parameter
(System\CurrentControlSet\Services\NSCService)".
"The subkey 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\NSCService' does not exist on the 'localhost' host".
"The step setDefaults with step key J2EE_SystemCopy_OneHost|ind|ind|ind|WebAs|640|0|J2EE_SystemCopy|ind|ind|ind|ind|0|J2EE_EngineEnterpriseDialogs|ind|ind|ind|WebAs|630|0|setDefaults was executed with statur ERROR".
And, when I clicked the View Log button, I got the following info.
SAPinst is getting started.
Please be patient ...
guiengine: no GUI connected; waiting for a connection on host VICKY, port 21212 to continue with the installation
guiengine: login in process.

I tried to re-install again, but faced with the same error.  Please suggest on how to go further. 
Thanks in advance.

hi Vicky,
Do you have admin rights to install? Access denied to Registry Key Editor means you don't have access permissions to open the registry.
you should be a part of administrator group to run the installation.
