Cause: the folder search read only the App Paths "Path" value, which this
branch introduced. 0.6.0 and earlier could already be installed elsewhere
with INSTALLFOLDER=..., but have no Path value, so an upgrade went to
Program Files while the wizard said it would stay in the same folder.
Fix: when there is no Path value, a second search reads the App Paths
default value (the full path of effectcraft.exe, written by every
release). A "file" registry search with no FileSearch inside yields the
folder of that file.
Tests: test-msi.ps1 installs a legacy package (the same .wxs without the
Path value) into a custom folder, then upgrades it without naming a
folder; it fails on the previous .wxs (the upgrade lands in Program
Files) and passes now. A further upgrade checks the Path value route.
A fresh install opens on a destination page (Program Files by default;
Change... browses, with Up and New folder), then a Ready page that shows
the folder before anything is written. An upgrade goes straight to the
Ready page with the installed copy's folder and can't move it; opening the
MSI again offers Repair or Remove. Cancel, finish, files-in-use and error
dialogs are authored too. Silent installs (/qn) show none of it.
The dialogs (installer-ui.wxs) are original, built from Windows Installer's
own controls and events, not the WixUI library, whose MS-RL licence is not
on the allowed list. package.ps1 builds both .wxs files.
The MSI records its folder as the App Paths "Path" value of effectcraft.exe
and reads it back with a registry search, so an upgrade, a repair or a
silent reinstall goes where the installed copy already is. A folder passed
on the command line (INSTALLFOLDER=...) still wins, and INSTALLFOLDER is
Secure so a folder chosen in the UI reaches the elevated install. v0.6.0 and
earlier have no Path value and upgrade in Program Files, where they are.
The MSI Icon id had no .ico/.exe extension, which Windows Installer needs for
advertised shortcuts and ARPPRODUCTICON, so both showed a blank icon. Release
builds of the desktop app are now GUI-subsystem (no console window; the CLI stays
a console program), the shortcut/summary description names what EffectCraft does, and
packaging-lint rejects an Icon id without an extension. Found in printcraft#57.
