TOXCHEM+ FAQs

Demonstration mode

Q

Why does TOXCHEM+ only run in "Demonstration" mode?

A

TOXCHEM+ runs in demo mode unless a licensed hardlock device is installed. If you have a hardlock key installed, the most likely cause is out-dated or improperly installed hardlock drivers. Ensure that you are using the latest release of TOXCHEM+ and the most recent hardlock driver files.

NOTE : Version 3 of TOXCHEM+ is not compatible with Version 2 hardlocks. Also ensure that you have administrative privileges to install any drivers under WinNT/2000/XP.

Download the latest release of TOXCHEM+ V3, the last release of TOXCHEM+ V2 or most recent hardlock drivers.

example.wtp error

Q

When I run TOXCHEM+ I get a message "Cannot open file example.wtp.

A

If you have manually created a shortcut to Toxplus3.exe, the program will use the location of the shortcut as the current directory and will not find the example file. Follow the steps below to ensure that the "Start In" directory for your shortcut is your TOXCHEM+ 3 directory :

1. Right-click on the program shortcut.

2. Select "Properties" from the speed menu.
3. In the "Start in" entry box type the path to the Toxchem+ 3 directory. (It will be the same as the shortcut path without the "toxplus3.exe".)
4. Click "Apply".

Mass balance failure

Q

Why do I see "Mass Balance Failure" when I run TOXCHEM+?

A

One of the flows leaving a process is greater than the influent flow. Check flows around the failed process and try running again.

Network

Q

Why does TOXCHEM+ run in "Demo" mode over my network?

A

You require a network hardlock (pink and green key) to enable TOXCHEM+ to run in "full" mode over your network. If you have a network hardlock, consult the following checklist :

1. Ensure that the hardlock key is firmly attached to the parallel (printer) port on the hardlock "server" computer.

2. Ensure that you have the most recent releases of the hardlock device drivers and HL-Server.
3. Check that the HL-Server program is running on the "server" computer. (Use Task Manager in WinNT/2000/XP).
4. Check that the HL-Server start-up settings are correct :
          - Right-click on the HLS32 icon in the start up folder.
          - Select "Properties".
          - Look at the "target" line for the shortcut. If you are using IPX/NetBios (defaults) for the hardlock,
            the line should appear as follows :
            Win9x/Me :  "[Drive:]\Program Files\HL-Server\Hls32.exe" -m:24969 -c:IPX,NetBios -e:NetBios
            WinNT/2000/XP :  "[Drive:]\Program Files\HL-Server\Hls32svc.exe" -m:24969 -c:IPX,NetBios -e:NetBios
   If you have manually enabled TCP/IP, everything after -m:42969 SHOULD BE REMOVED.
   Edit the line accordingly.
5. Check that you have the correct Environment settings. If you are using IPX/NetBios (defaults) the following line should appear in your autoexec.bat (Win9x) or your Environment Variables(Win NT/2000/XP) :
   SET HL_SEARCH=278p,378p,3BCp,IPX,NetBios
   If you have enabled TCP/IP manually, this line SHOULD BE REMOVED from the autoexec.bat file (Win9x/NT/2000/XP) AND the Environment Variables (Win NT/2000/XP).
6. Restart the "server" computer after making any of the above changes..

Internet connection

Q

Why does TOXCHEM+ try to dial my internet connection?

A

Single-User / Demo:

1. Check your autoexec.bat file (Win9x) or your Environment Variables for the following line :
   SET HL_SEARCH=278p,378p,3BCp,IPX,NetBios

2. If this line is not present, please add it.
3. Restart your computer.

Network:

1. The dial-up window may appear if you have enabled TCP/IP for a network hardlock. (The TOXCHEM+ installation program disables TCP/IP by default.) If you must use TCP/IP, there are a couple of ways to prevent the dial-up window from appearing when you start TOXCHEM+. The most likely cause is that another program has replaced your Windows WINSOCK.DLL file with one of it's own. The quickest fix is to copy the original WINSOCK.DLL from your Windows disk over the new one. (It's located in the Windows directory.) If this is not an option, you can specify a static IP address for the hardlock "server" computer, and then add the following Environment Variable: (Add to autoexec.bat in Win9x.)

2. SET HLS_IPADDR=255.255.255.255
   (The address above should be replaced by the IP address of the network hardlock.)
3. Restart your computer.

Novell network

Q

Will TOXCHEM+ run over a Novell network?

A

Yes. TOXCHEM+ will run on any computer using Windows 9x/Me/NT/2000/XP operating systems regardless of the underlying network architecture. Network copies of TOXCHEM+ can run over a Novell network provided the hardlock key and server utilities are installed on a Windows-based workstation. To install HL-Server on a Novell server, contact Hydromantis, Inc. support.

Windows XP

Q

Will TOXCHEM+ run on Windows XP?

A

Yes. The latest hardlock drivers do support Windows XP. Download the latest hardlock drivers.
