Default Add-in error after uninstall

After uninstalling an Exchange Client Extension it's possible to get the
message "The add-in *** could not be installed or loaded. This problem may be
resolved by using Detect and Repair on the Help menu" when starting Outlook.

This happens on multi-user systems because the instruction to rebuild the
add-in cache (extend.dat) is a machine-wide registry value and only the first
user to start Outlook gets their cache rebuilt properly.

Does anyone have a solution for this besides deleting extend.dat for every
user?

Note: The machine-wide value I'm referring to is:
HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\Cli ent\Extensions\
4.0;Outxxx.dll;7;000000000000000;0000000000;OutXXX
Outlook deletes this value after reading it, so subsequent users don't see it.

There is no solution otegr the ndeletign extend.dat for all users. This is
really an architerctural problem tha tcannot be fixed easily.
Switch to a COM add-in if you can.
