Check that your shortcut is correct:
On a local installation the path is c:\program files\datatex\topaz
In the shortcut it must be in double quotes (") because there is a space
in the name. So it should look like this:
"C:\Program Files\Datatex\Topaz\topaz.exe" "C:\Program files\datatex\Topaz\Data"
If you still have this problem try the following:
Try using the windows short names:
c:\progra~1\datatex\topaz\topaz.exe c:\progra~1\datatex\topaz\data
Try the instructions for a client installation. After that, you should
have a shortcut that will point to the network PC, which should not
contain any spaces.
