rpcclient from tng

[Seth Vidal]

hi folks,
 I know this is a more mundane question than the current controversy
but...

I downloaded and built tng (well rpcclient out of tng at least) and I've
connected into an NT machine to registry edits.
the situation:

HKLM\SOFTWARE\COMPANYNAME\SOFTWARENAME\LICENSEKEY\

the only (default) key under this tree is a string type licensekey.

How do I set the value for the default entry?
As well when I do a regenum It never lists the  current value.
the errors I see:
[skvidal at JORDAN]$ regenum "HKEY_LOCAL_MACHINE\SOFTWARE\PASCO
Scientific\DataStudio\LicenseKey"
regenum "HKEY_LOCAL_MACHINE\SOFTWARE\PASCO Scientific\DataStudio\LicenseKey"
vuid_init_db: failed
Key Name:   HKEY_LOCAL_MACHINE\SOFTWARE\PASCO Scientific\DataStudio\LicenseKey
Key Values
----------
REG_ENUM_VALUE: 

[skvidal at JORDAN]$ regenum "HKEY_LOCAL_MACHINE\SOFTWARE\PASCOScientific\DataStudio\SerialNumber" 
regenum "HKEY_LOCAL_MACHINE\SOFTWARE\PASCO Scientific\DataStudio\SerialNumber"
vuid_init_db: failed
Key Name:  HKEY_LOCAL_MACHINE\SOFTWARE\PASCOScientific\DataStudio\SerialNumber
Key Values
----------
	:	string:	5895


so you see the next key does have values but the licensekey doesn't.

I've checked the machine and there is an entry.

what does vuid_init_db: failed mean?

thanks
