Hi Bo,

Use the Shell command to launch regsvr32.exe (which is in the
C:\WINDOWS\system32 folder), with the ocx's path and filename as a
parameter.

If there are no spaces in the path, something like this will work:

  Shell "regsvr32 c:\windows\system32\asctrls.ocx"

If there are spaces, you need to include quotes around the
path/filename as part of the parameter. To do this, represent the
quotes as Chr$(34) like this:

  Shell "regsvr32 " & Chr$(34) & _
      "c:\program files\quicktime\qtplugin.ocx" _
      & Chr$(34)
