Error: 1733: Class definition TELEMAGIC.DOWNTIMEMONITOR is not found

This error has to do with the user access rights.

This generally occurs with a new PC, attempting to run TM5 for the first
time. It’s looking for DTMON.DLL in the System32 folder.


Make sure the user has Power User rights and it should work fine.

Either manually copy it into the System32 directory on the PC in question from the server or do this:

  1. Log into the local machine with administrator
  2. Run DBUTIL on the local machine and run Register System Files
  3. Exit out of DBUTIL
  4. Run TeleMagic v5
  5. Exit out of TeleMagic
  6. Log off Administrator and log in as the user
  7. Run TeleMagic v5

When all else fails install an eval copy of TM to a different directory (c:\tm5delete) once installed try running the client again.  Sometimes the eval install seems to do a better job of getting the files registered and setup correctly than copy and register system files does


Error: “an unknown error occurred while loading Tm.exe. shutting down”

I have a client who just bought a laptop with Win 7-32-bit and he gets ‘an unknown error occurred loading TeleMagic. Shutting down.’


Most common error has to do with the fax driver, or the fact that the user doesn’t have rights to update files in the system32 folder.

Check to make sure you have admin rights on the machine, for the first time you run TM.

Log in as the administrator, and run  the copy/register. After that is done, try it again.

When you install TM5 on a W7 or W Server 2008 you must copy from somewhere the telemagic folder that is in c:\program files\telemagic

There are fax files and folder in there that does not get created on install.  If it is a 64 bit OS you would copy it over to the c:\program files (x86) folder.

This telemagic folder is often overlooked because on a XP install we never notice it is there.

If this is a Terminal Services installation, set the Check System Files to N in TM.INI
