c# 4.0 - Silverlight 4 WScript.RegRead failing to read newly added value in registry under Windows 7 -


i have silverlight 4 application in can read existing registry values hklm branch no problem if add new value read fails filenotfoundexception. can see in code below; first read works fine second 1 fails read test value added in registry.

note: able read newly added key under windows xp; not under windows 7.

any appreciated.

if (application.current.installstate == installstate.installed && application.current.haselevatedpermissions) {     if (automationfactory.isavailable)     {         dynamic shell = automationfactory.createobject("wscript.shell");          try         {             var resa = shell.regread(@"hklm\software\microsoft\.netframework\installroot");             var resb = shell.regread(@"hklm\software\microsoft\.netframework\test");              var regvalue = shell.regread(dbtyperegkeyname);             var dbtype = extractdbtypefromid(regvalue);         }         catch (filenotfoundexception filenotfoundexception)         {             throw new exception(string.format("failed read registry value '{0}' error '{1}'.", dbtypevaluename, filenotfoundexception));         }     } }

worked okay under 32 bit version of windows. turns out 64 bit version of windows has different view of registry. adding key under wow6432node key in registry solved problem.
