I use RT. I’ve poked at DT a few times but I didn’t want a built in DAM. So I was interested in a recent thread that pointed out that one could dispense with the database by using the --library :memory: option.
So I installed DT 4.2.1 on my Windows 10 system.
If I click on the desktop shortcut created on installation, DT starts without issue. However if I try to start DT from the command line (or in a batch file) using something like “darktable filename”, DT doesn’t start. It will only start if I set “run as administrator” on the dartable exe file. But then I get a Windows popup asking “Do you want to allow this app from an unknown publisher to make changes to your device?” For various reasons this is not, in general, satisfactory. How can I avoid this issue?
I’m probably doing something stupid but it’s not obvious to me what it could be.
You need to use the full path to the darktable.exe file, probably something like C:\Program Files\darktable\bin\darktable.exe

Actually, I am. I was just trying to describe things as simply as possible.
I am calling DT from PhotoMechanic via a simple batch file that consists of a single line:
“C:\Program Files\darktable\bin\darktable.exe” %1 --library :memory:
This works if I set DT to run as administrator but not otherwise.
For comparison, here is the batch file I use for RT:
“C:\Program Files\RawTherapee\5.9\rawtherapee.exe” -R %1
This works without settibg RT to run as administrator.
I need to use batch files as it is the only way to set --library :memory: or -R.

Maybe set things to – configdir “path” to a separate config folder …two options DO this just to check if the creation of a temp database in memory with the memory option truly needs admin. If running it this way works without triggering admin it must be that the nature of the virtual temp database created by the memory option needs admin access…
Then you could proceed this way and just delete the folder whenever you don’t need it or empty the contents from time to time as needed… Note the dam in darktable is a relatively small database that only keeps the setting of the edits which are mirrored in the xmp files… its not going to really be a big issue to have it…

I altered the properties of the shortcut created by the darktable install, because lazy me likes to click an icon.
On the Shortcut tab, I changed the Target: field to"C:\Program Files\darktable\bin\darktable.exe" --configdir "D:\someguy\Pictures\darktable\config" --library :memory:
I do not have to run it as administrator.

Maybe getting the config files outside the Appdata folder is the key to avoiding the scrutiny…

Well, I’m not making much progress.
If I navigate to the folder C:\Program Files\Camera Bits\Photo Mechanic Plus and run the command
`C:\Program Files\Camera Bits\Photo Mechanic Plus>"C:\Program Files\darktable\bin\darktable.exe" "C:\Users\inbox\photos\tmp20230211\20230211-0086.orf" --library :memory:`
it works as expected when darktable is not running as administrator.
I modified my batch file to:echo %1 "C:\Program Files\darktable\bin\darktable.exe" %1 --library :memory: pause
When this batch file is fired by Photo Mechanic, I see the following in the cmd window:
C:\Program Files\Camera Bits\Photo Mechanic Plus>echo "C:\Users\inbox\photos\tmp20230211\20230211-0086.orf"
"C:\Users\inbox\photos\tmp20230211\20230211-0086.orf"
C:\Program Files\Camera Bits\Photo Mechanic Plus>"C:\Program Files\darktable\bin\darktable.exe" "C:\Users\inbox\photos\tmp20230211\20230211-0086.orf" --library :memory:
C:\Program Files\Camera Bits\Photo Mechanic Plus>pause
Press any key to continue . . .
But darktable doesn’t start. If I run as administrator, it does.
When I modify my batch file to
echo %1
"C:\Program Files\darktable\bin\darktable.exe" %1 --configdir "C:\photos\darktable\config" --library :memory:--library :memory:
pause
then darktable crashes whether I run as administrator or not. (But I just defined that location. I did not move any configuration file there because I couldn’t find one.)
Here is the crash report:
this is darktable 4.2.1 reporting an exception:

I see for some reason you are using the library memory switch 2x?? I am not sure what the interaction is… I would just run it with a configdir and empty that folder at the end or your session or occasionally… give up on the memory for now… clearly there is some interaction in that mode both with your permissions and the PM software…

We probably need to take a break from this for the time being. Where I’m currently at is that even if I reduce my batch file to the single line"C:\Program Files\darktable\bin\darktable.exe",
Therefore it looks as though there is something about how PhotoMechanic launches the batch file which gives rise to the problem. However, there is no problem with PhotoMechanic launching a batch file to run RawTherapee, an entirely parallel situation.
I will make some inquiries of PhotoMechanic and see if they have any comment.
