Preferences.txt File location

[micheus]

if the Preferences.txt file could be saved in the same folder as the Wings3d.Exe file. Maybe this is not possible with Windows permissions the way they are these days???

Yes, that would be a problem. But, if you install Wings3d in another directory than C:\Program Files or C:\Program Files (x86) (or any other system folder) you will not have this problem.

You have also the option to create different shortcut and indicate the use of a preference file for it.

Can I run Wings with kind of additional parameter, debug or something "safe mode"?

Yeah. You can try start wings by the command line so you will have the Erlang console back. Maybe it can stays opened after the crash and you can see any message on it.

Use the windows Prompt console for that (cmd.exe) and enter a line like this:
"C:\Program Files (x86)\wings3d_1.5.3\bin\werl.exe" -run wings start_halt -extra "C:\Users\<user name>\AppData\Roaming"

I used the directory for the current preferences file, but you can use any other as you can see in the dgud's post.

Maybe a setting could be added in Edit Preferences to choose a name and location for the Preferences.txt file.

File->Save Preferences Subset/Load Preferences Subset - Couldn't they help with this?
