I am using Installshield 2011.
When calling the function RegDBGetKeyValueEx() i am getting error code -2147024894.
What may be the reason for this?

See my script below.

C#

#define REGDB_SYS_ENV				"SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment"
function NewRegValues(szName, szDir)
    string szValue, szTmp,svType,svTmp2;
    NUMBER test,flag;
begin
       //--------- set Registry root to HKEY_LOCAL_MACHINE -------------//
	test = RegDBSetDefaultRoot( REGDB_ROOT_LOCAL_MACHINE );
	nTemp2 = -1;
	nTemp = REGDB_STRING_EXPAND;
	flag = RegDBGetKeyValueEx( REGDB_SYS_ENV, szName, nTemp, szValue, nTemp2 );
	if (flag < 0) then				
	  LogInstallationErrorToFile("ERROR:RegDBGetKeyValueEx failed to get ");

Do you mean to refer a single value? Now it looks like you're trying to get a key value from a whole node. Should the path be something like:

#define REGDB_SYS_ENV				"SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment\\OS"

or whatever key you're trying to use.
