Windows Installer: Update Some Install Paths

Installer Design for Windows

Before the installer script installs OpenAdapt, it first runs checks for 3 dependencies in the following order:

• Tesseract
• Python
• Git

Program	Current Path	Proposed Path	Remark
Tesseract	C:\Program Files\Tesseract-OCR	C:\Program Files\Tesseract-OCR	No change
Python1	C:\Users\<user>\AppData\Local\Programs\Python\Python310	C:\Users\<user>\AppData\Local\Programs\Python\Python310
Git	C:\Program Files\Git\	C:\Program Files\Git\	No change
OpenAdapt	C:\OpenAdaptSetup\OpenAdapt	C:\Users\<user>\OpenAdapt	Changed

The installer script already expects to be executed with Admin privileges but the 'InstallAllUsers=0' option used to install Python will put it under C:\Users\$user\%LocalAppData% for the logged in user, unlike the other dependencies where the install path is global -- for all users.

I experimented with the option to install Python for all users to C:\Program Files\Python310 by setting 'InstallAllUsers=1' and everything worked fine until it got to the poetry install step where the script failed with a path-related error so I changed it back to 'InstallAllUsers=0'.

Thoughts?

Motivation

This will hopefully make it easier to write an uninstall.ps1 script that will leave the system in the state it was prior to the execution of installer.ps1.

Footnotes

1. The default path is C:\Users\<user>\%LocalAppData% which usually expands to C:\Users\<user>\AppData\Local\Programs\Python\Python310 ↩
