Upgrading from Wordshark (Original), Wordshark 2 or 2L, or Numbershark (Original)
These were designed for DOS machines, and do not work with operating systems more recent than Windows 98. They are no longer supported, other than for upgrade advice.
Their data cannot be imported into later Wordshark or Numbershark products.
If working, they may be left on the computer (if already installed), or removed. To remove, delete the program folder (usually c:\NSHARK or c:\SHARK) and any desktop icon. These are very old DOS programs, so are unlikely to feature on the “add/remove programs” list.
