Check if the Excel version you are running is 32 or 64-bit version. The installed MBAXP must match.

32-bit Windows:

  • 32-bit mbaxp.ocx is installed in c:\windows\system32
  • 64-bit mbaxp.ocx can't be installed

64-bit Windows:

  • 32-bit mbaxp.ocx is installed in c:\windows\SysWOW64
  • 64-bit mbaxp.ocx is installed in c:\windows\system32

(Note the stupidity of it all — the default regsvr32 is 64-bit and resides in the \windows\system32 directory. Note the "32" in system32 and the "32" in regsvr32 — quite misleading. However the 32-bit version of regsvr32 is found in the \windows\syswow64 directory. Note the "64" in the directory name. That’s also misleading.)

To run the 32-bit regsvr32, do this:

cd \windows\syswow64
regsvr32 mbaxp.ocx

To run the 64-bit regsvr32, do this:

cd \windows\system32
regsvr32 mbaxp.ocx

You must run the command prompt as administrator.

A simple solution if you want to run the command prompt as administrator is to open the Start Menu, type in "cmd"" in the bar along the bottom, then instead of just pressing enter, press CTRL+SHIFT+ENTER instead. It will then show up as ""Administrator: Command Prompt" in the window title.
