My darktable 2.6.2 doesn’t start anymore. I see the CMD for a fraction of a Second, and that was it. I did already a uninstall (more then once) but it still doesn’t start after new installation.
I do have also 2.7dev on an external HDD (usually not connected) and I presume that 2.7 [censored] the 2.6.2 installation (by overwriting the db?).
Strange thing is, I don’t see much darktable remains on the main drive, so I wonder what it won’t start. There must be some hidden remains somewhere.
I will keep 2.7dev, but not force it to a portable.db with its folder on the external drive.
…a few hours later…
I managed to make 2.6.2 (a new install) run again by delete \user…\darktable\ directory. So 2.6.2 is fine again.
However, the 2.7 dev version still wants to use the same data.db. The --library command has no practical effect, it creates the db, but doesn’t use it.
So how to make 2.7 run without [censored] up 2.6.2?
At this point, a huge praise to the Rawtherapee team for providing zip installers for all dev versions, that all run fine in parallel
