Bootstrap : get path to TD executable not working

[Scelibre]

``Describe the bug
I had a problem, the bootstrap could never find TouchDesigner even though it was installed, it reinstalled it each time which was very annoying. I fixed this problem on my PC but I don't know if it will work for everyone.

Desktop:

• Device: Asus Computer
• OS: Windows 10 Pro - 22H2 (19045.3930)

These changes resolved the issue:

...
:: IF registry entry exists, get path to TD executable and set to variable td_executable_path
:: Next, trim off the last 5 characters to get the pure path. !! characters are used for DelayedExpansion
reg query %registry_query_str% >nul
if not %errorlevel% equ 0 goto InstallTD

FOR /F "usebackq tokens=3,* skip=2" %%L IN (
    `reg query %registry_query_str%`
) DO SET td_executable_path=%%M
SET td_executable_path=!td_executable_path:~0,-5!

if exist !td_executable_path! goto ReadyToLaunch

:InstallTD
