After an upgrade to 3.3.16.1, using the options listed below, the Registry key that stores the "User Include Folder" (HKEY_CURRENT_USER\SOFTWARE\AutoIt v3\AutoIt) is gone and I have to use Tools -> SciTE Config to set it back to the original value. All my other AutoIt and SciTE options/setting were left unchanged.
Before Upgrade:
"HKEY_CURRENT_USER\SOFTWARE\AutoIt v3" had a subkey "AutoIt" with a REG_SZ value of "Include" which was my "User Include Folder" path.
Reg Export:
[HKEY_CURRENT_USER\SOFTWARE\AutoIt v3\AutoIt]
"Include"="C:\\HotRod\\AU3\\_INC"
After Upgrade:
There is no "AutoIt" subkey under "HKEY_CURRENT_USER\SOFTWARE\AutoIt v3" and the "User Include Folder" field in SciTE Config is blank.
Upgrade Options:
Uninstall before continuing
Use native x64 tools by default
Default for *.au3 files = Edit the script
Type of install: Full
Destination Folder: C:\Progs\Apps\AutoIt
