XLL+ Class Library (7.0)

Requirements and deployment

The RTD implementation of object handles uses Excel's RTD mechanism. An add-in that uses the RTD handle implementation therefore has some runtime requirements on any machine where it is to be used.


Excel version
Excel's RTD mechanism is only available in Excel XP upwards (Excel XP/2002, Excel 2003 and Excel 2007). It cannot be used with Excel 97 or Excel 2000.


The model uses a COM module (RtdHandleServer.dll) to support Excel's RTD mechanism. You should register the RTD server module RtdHandleServer.dll, in one of the following ways:

  1. Use REGSVR32 at the command line, e.g.
    REGSVR32 "C:\Program Files\Planatech\XllPlus\6.0\VS9.0\bin\RtdHandleServer.dll"
  2. Build the project Samples\RtdHandleServer\RtdHandleServer.sln. Choose either the Debug or the Release MinDependency build.

Note: The RtdHandleServer DLL is automatically registered when you install the XLL+ toolkit on a development machine. You only need to register it yourself when you deploy XLLs with RTD object handles to another machine.


If you are unable to satisfy these requirements, you can consider using an alternative object handle mechanism. See Other handle implementations for details.
