TOPIC:

I believe this issue has been raised before, but I'll reiterate: when will the IDE's main appearance settings (color theme, editor font, window placement, etc.) be preserved when updating the CT version? As far as I understand, this can be accomplished by literally changing a couple of lines of the installation script (avoid deleting files in the settings directory), and this will almost always work (unless the configuration file format is drastically changed).

We can't provide a total solution.
Every new CT release has new Settings Elements

I haven't had to restore my colors for a while now, but these are the notes I made.  You have to have saved your colors into a file before hand, of course:

Restore colors in Codetyphon:
1) Put your new "color file (mine is named C:\CodeTyphonProjects\testcolors.xml)" at:

C:\Users\myusername\AppData\Roaming\typhon32\userschemes\testcolors.xml
or
C:\Users\myusername\AppData\Roaming\typhon64\userschemes\testcolors.xml

Folders

2) Close Typhon IDE and Reopen the IDE (or Typhon IDE Menu => File=> Restart)
Typhon read all "color files" list from above folder at IDE start up.

3) Go to IDE Settings Option=>Display=>Colors>Third tab over>Select testcolors.xml
and select you new "color file"

When I install a new version of Typhoon, I do it like this:
1) I'm saving these three files in the image.
2) I'm installing the new version of Typhoon.
3) I start Typhoon and set up the docking windows.
4) I close Typhoon and copy the three previously backed-up files back to their original positions.

After that, everything works as before.
