You may install Version 5, Version 4 and use on the same computer, but the following limitations apply:

• Installation
  
  Version 5 cannot and should not be installed to the same folder.
  You should not copy program and DLL files from the Version 5 folder to the Version 4 folder and vice-versa.
  You should not use setup files created and used by Version 5 in the Version 4 software.
  
  
• Running Programs
  
  You can run either Version 4 or Version 5 at once, you cannot run both programs at the same time.
  Only one of version 4 or 5 can be set to autostart when the computer starts.
  If you start Version 5 while Version 4 is running, Version 4 will be automatically closed.
  
  
• Setups
  
  Version 5 setups are independent of Version 4, apart from some PLC interface settings.
  To ensure you can go back to previous Version 4 settings, keep an up to date Setup Manager Tools Backup in case it is necessary to use it to return to previous settings.

  Version 5 uses the same default passwords as Version 4. If you have imported a Version 4 job, the passwords will be those of Version 4. If you make changes with the Version 4 Setup Manager, these changes will not be brought through into Version 5, unless another Import V4 Installation is done.
  
  

• Data Storage and Disk Space
  
  If  you import the complete V4 Installation into Version 5, you must have enough disk space for a second copy of the store files that Version 5 will use. Additional space is required for new store files and Log Files.
  There is no support for running Version 4 and Version 5 at different times and combining the data or store files from both programs together.
  
  
• Networking
  
  On a Networked System, all actives and passives need to be upgraded to Version 5.
  
  
• To Auto Start Version 4, and not Version 5
  
  1. Disable Auto Start on Version 5
  
  On Setup Tools, click Program Startup, click "Start MicroScan when Windows Starts" off.
  Click OK.
  Close Version5
  
  2. Enable Auto Start on Version 4
  
  Run Setup Manager
  Click System Setup
  Click "Start MicroScan 2000 when Windows Starts" on.
  Click OK.
  
  Restart Computer to test.
