 Program says “ActiveX Not Found”


 1) Win95/98, contact Hds and report the missing name.
 2) WinNT, Minimum version and service must be 4.0 SP5.    WinNT 4.0 SP3 does not allow ActiveX registration so   NO Windows Registry items under    "HKEY_CURRENT_USER\Software\Hydrocarbon Data Systems, Inc\ HDS2000\User0" will be writeable.
3) Running calculations requires the Microsoft VB scripting support and the script control. These processes are done after the initial CD installation the first time you run the program.

To load these modules:
    Exit HDS 2000.
    Go to "C:\HDS2000\ENGINES".
    Copy the text file "HdsScript.Txt" into \HDS2000.
    Restart your program and install these controls. (rebooting is probably not required).
