To update MailBee64.dll to a newer version (assuming it's installed in the default location):

- If you're using MailBee under IIS/ASP, reset IIS by typing iisreset in the command line

- un-register the version currently registered. Type the following in the command line:

  regsvr32 -u "C:\Program Files (x86)\MailBee Objects\MailBee64.dll"

- replace MailBee64.dll with the newer version

- register the new version:

  regsvr32 "C:\Program Files (x86)\MailBee Objects\MailBee64.dll"

Notes:

- if you're replacing registration of 32-bit version (MailBee.dll) with 64-bit version
(MailBee64.dll), then you should un-register MailBee.dll and then register MailBee64.dll.
You can, however, have both MailBee.dll and MailBee64.dll be registered side-by-side
(for instance, MailBee Objects setup program installs and registers both 32-bit and 64-bit
versions of MailBee.dll if your OS is 64-bit).

- if you're manually registering MailBee64.dll and have not registered anything before
(i.e. not even ran MailBee.exe installation program which automatically registers MailBee.dll)
you don't need to un-register anything.

- if you run Windows Vista/2008/7/8/2012 with UAC enabled, use 'Run as Administrator'
when opening the command line. UAC might not allow using regsvr32 to any user except
of Administrator even if that user has administrative privileges.

- in x64 Windows, two versions of regsvr32 may exist. Use the one in Windows\System32 folder
and do NOT use the one in Windows\SysWOW64 folder.
