You probably have a new FIMS workstation. This problem is not uncommon. Windows is not allowing FIMS to register 2 files in the windows folders. This is how to do it manually:
  1. Close out of FIMS.
  2. In the Windows Start menu, type cmd in the search field and click the program it finds.  
  3. Type in the following lines one at a time and hit enter after each one. 
    1. copy n:\found\fims\tview4gl.ocx c:\windows\syswow64
    2. copy n:\dlc\bin\prox.dll c:\windows\syswow64
    3. cd c:\windows\syswow64
    4. regsvr32 prox.dll
    5. regsvr32 tview4gl.ocx
  4. ​Close the command prompt.
  5. When you restart FIMS you should no longer receive this error. 
Note: If you get an error about c:\windows\syswow64 being a bad directory or not found then change the paths used to c:\windows\system32.
