What’s New in This Update

Ooops, we made a mistake in an email about FoCal 2021 Release Candidate and may have sent you here by mistake! The correct release note for FoCal 2021 RC is here.

Welcome to FoCal 2020 RC. This is the Release Candidate for FoCal 2020, meaning it is very close to the final, stable version.

Version Details

ComponentVersionTypeRelease Date
FoCal – Windows & Mac3.0.4.8622RC (Beta)23rd October 2020

Headline Features

There have been a number of bug fixes and improvements since the last Beta version.

The most obvious difference is for Windows users: FoCal is now a pure 64-bit application which fixes some reliability issues for some long running, processing intensive tests.

The following are a few key changes in other areas:

  • CSV output has been improved and added to tests that didn’t support it
  • File mode support for various cameras has been improved
  • We have fixed some camera control issues after thorough testing with over 25 cameras.

Known Issues

All Platforms

  • Nikon D700 does not connect – this will be resolved in the next build.


  • Processing of User Metadata file (meta.json) in file mode does not work on Mac. This is an advanced feature and will be reworked for the next major release.
  • User Interface Zoom setting does not work well.


  • The first time a brand-new installation is run you may see an error about “being unable to write to the transport connection.” This only occurs once, so restart FoCal and you will not see the message again. We are investigating this issue.
  • We have had a couple of reports of Live View not starting for Target Setup. This is being investigated.

Windows Prerequisites / Installer Problems

Note that for all of the FoCal 2020 releases we have had no reported issues with the Windows installer not correctly updating dependencies, so we will remove this section in the next release notes if no reports are raised.

The Windows Installer should automatically install any necessary missing prerequisites on the first installation, but if you have problems with the installer you should manually install the following:

.NET Framework 4.8: https://dotnet.microsoft.com/download/dotnet-framework/thank-you/net48-web-installer

FoCal is now a 64-bit application on Windows, so you would need the 64-bit Visual C++ redistributable files:

Visual C++ Redistributables (x64 version): https://aka.ms/vs/16/release/vc_redist.x64.exe

If you download and run the installers for both of the above, and then re-run the FoCal installer it should fix any issues.
