It means "window access failed". i.e. something about displaying the test color failed.

Without a more detailed debug log, it's impossible to say more.

I'm still working towards it - there are a couple of new instruments and other changes in the pipeline ahead of it.
(The functionality is present in ArgyllCMS V1.7).

Please point out a more up to date report by an independent third party, that addresses all your criticisms.

Can't find one ?

How about doing it yourself then ?

It won't affect emissive (it only use black point calibration), but reflective will certainly be mis-calibrated.

The Spyder4 & 5 instruments don't come with CCSS files, they come with some near-equivalents that are in the .bin file that oeminst creates. If you have CCSS files from other sources (i.e. you have...

You need to use the oeminst that comes with ArgyllCMS V1.7
(Presumably HCFR needs updating, or perhaps you aren't using the latest version)

And how visible is an error of 0.012 in red going to be ?

Taking 1 second per reading, measuring patches with all combinations of 12 bits would take about 2200 Years.
Have you got that long ?

Feel free to want to do that when using LightSpace.

There's no demonstrable need when using ArygllCMS/ColorMeter/HCFR though, since a different driver is being used. (Check out...

It's not possible within a single reading, because the hardware imposes a maximum time of 20 seconds. Taking multiple readings wouldn't help much, as you can't measure a frequency when zero or one...

That's a lot of work and extra complexity in the code, UI & documentation, just so you can play around.

Most meters use adaptive integration time by default, so there is no particular integration time to change.

But what specific problem are you trying to solve ?

I've tried that approach (with a different instrument), and it doesn't work, or would take far too long because what you are trying to detect is buried in measurement noise.
