What to do if my REX, or REX Tools, or Intellisync keeps crashing or locks up when you try to sync.

From a REX Rumor Central contributor (thanks MK!) who talked to Xircom about his troubles. Here's what he got, and it fixed his problems. Read the whole page before you do anything!

Before you embark on the extensive steps below, try one simple fix to repair a REX that is crashing, or a REX Tools that won't start successfully.

  1. Insert your REX into your cradle or PCCard slot
  2. Start REX Tools WHILE HOLDING DOWN THE LEFT SHIFT KEY!!
  3. Use REX Tools to Initialize the REX (this clears all data and settings on the REX)
  4. Close REX Tools and start Intellisync
  5. Reconfigure Intellisync (all settings are lost when you initialize the REX) and sync your REX

For some users, this will do the trick. If it doesn't help you, dive into the more detailed and complete steps below. Good luck!!

Ok, for everybody who is experiencing crashing REX, REXTools crashing so you can't reset your REX, crashing Intellisycn, etc.), the following fix seems to work. Problem is, it requires editing your Windows Registry. If you don't understand what that means, probably best to stop now and find your friend who does "get it" and ask him/her to help. Here goes ...

  1. Uninstall for Rex6000 software/USB Docking station.
  2. Uninstall everything in Add/Remove Programs that relates to Xircom and Rex. Also uninstall the listings for the Xircom Rex USB docking station if they are listed also. If you are ever prompted do NOT restart the computer.
  3. Delete the Rex6000 folder from C:\Program Files
  4. Search your local harddrive for rex* and delete any of the following files that are found within the C:\Windows\System (or C:\WinNT\System) and C:\Windows\System32 (or C:\WINNT\System32):
    • REX.DLL
    • REXDB.DLL
    • REXSERA.SYS
    • REXSERE.SYS
    • REXSERU1.INI
    • REXSNUM.VXD
    • rexuinst.exe
    • REXSERPG.DLL
    • REXSERPG.HLP
    • REXVCD.VXD
    • REXVSERD.VXD
    • RexResource.DLL
    • REXShared.DLL
    • REXTool.DLL

  5. NOTE: If any of these files are in use (and Windows will tell you if they are when you try to delete them) skip them for now and go on thru step 6 (Restart Computer) and then repeat this step after the restart until they are all gone.
  6. Open Regedit (Start > Run > type REGEDIT). Be very careful here - you can really muck up your Windows installation if you screw up your registry.
  7. Delete the following keys in the registry. Remove the following registry entries:

    • HKEY_LOCAL_MACHINESoftwareXIRCOM
    • HKEY_LOCAL_MACHINESoftwareREX 6000
    • HKEY_LOCAL_MACHINESoftwareCLASSESAppIDRexPro xy.EXE
    • HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCu rrentVersionUninstallXirco m Rex 6000 Drivers and Online Documents
    • HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCu rrentVersionUninstallXirco m Rex 6000 Tools
    • HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCu rrentVersionUninstallXirco m Rex 6000, Intellisync for Rex
    • HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCu rrentVersionUninstallXirco m Rex 6000, PIM for Rex
    • HKEY_CURRENT_USERSoftwareXircom
    • HKEY_CURRENT_USERSoftwarePuma Technology
    • HKEY_CURRENT_USERSoftwareCITIZEN

  8. Restart your computer
  9. Re-install REX 6000 software
  10. Plug in USB docking station (if you are using it)
  11. Follow the Hardware Wizard for the USB install - tell it to look for the drivers in C:WindowsSystem (C:WINNTSystem32 for WIN2K). They should be there on your system by default after the REX/Intellisync software installation. If they are not found, then tell the hardware wizard to look in the subfolder on the CD that matches your Operating System.
  12. Insert the REX 6000 into the docking station/PC slot.
  13. Run REXTOOLS WHILE HOLDING DOWN THE LEFT SHIFT KEY!! Then initialize the card.
  14. Configure Intellisync for REX and procede normally.

The most important part of the whole procedure is HOLDING DOWN THE LEFT SHIFT KEY while starting RexTools.
