FastExcel V4 FAQ

What is FastExcel V4?

  • FastExcel V4 is a family of Excel addins to help you speed up, maintain and cleanup your workbooks.
  • FastExcel for Windows has 3 main components:
    • FastExcel V4 Profiler: Profiling tools to find and measure VBA and calculation bottlenecks in your workbooks. Additional Calculation Modes and timing tools to help you calculate only the minimum required
    • FastExcel V4 Manager: Formula Explorer, Workbook Cleaner and Name Manager tools to help you develop, debug, manage and maintain your workbooks.
    • FastExcel V4 SpeedTools: 100 high-performance multi-threaded functions to speed up your workbooks.
  • FastExcel Manager Pro for Mac Office 365

I have FastExcel V3 - what are my options?

FastExcel V3 is no longer supported or for sale.

Can I install FastExcel V4 at the same time as FastExcel V3?

This is not recommended. Profiler and Manager have been designed to coexist but this scenario has not been extensively tested. Coexisting V3 and V4 SpeedTools could cause problems because the names of many of the SpeedTools functions are the same across both versions.

Help! The FastExcel licensing wizard says I have used up all my activations.

  • Each activation is tied to the name of the PC.
    If you reinstall the operating system or change the name of your PC you should first release the FastExcel license (Excel->FastExcel->Licenses->Release These Licenses).
    But if you did not release the license before reinstalling or changing the name you can use our FastExcel Licensing Help Webpage to manage your activations
