Hi Larry!
At the client on this computer it is installed Win98 and VFP6.0 SP4.0 RunTime.
I use code to get serial number:
*-
oFSO = CREATEOBJECT("Scripting.FileSystemObject")
oDrive = oFSO.GetDrive("C")
nVol = ABS(oDrive.SerialNumber)
*-
During several months all worked perfectly, but today ...
at first line "Scripting.FileSystemObject is not found."
