Installed FormTracePak v6.213 on the win11 VM (picking FORMTRACER Avant
in the dialogs) and probed the resulting registry / disk layout to find
out what evidence a real FormTracePak install actually carries. Two
empirical findings:
1. ACTIVE MODEL lives at
HKLM:\SOFTWARE\WOW6432Node\Mitutoyo\FORMPAK\Config\device map\DeviceName
(string value). For the AVANT install the value is "FORMTRACER Avant";
for the CV/SV/CS controllers the value contains the matching model id.
The Surfpak\FormMes\MachineInfo\Machine\Machine* subtree lists EVERY
supported machine and is NOT the active selection - the previous
heuristic that scanned uninstall-entry DisplayName picked up bogus
WinUSB driver-package entries from "Mitutoyo Corporation" instead.
2. INSTALLED BINARY VERSION is in Formtracepak.exe VersionInfo:
FileVersion=6.2.0.51, ProductVersion=6.2.0.0. This does NOT match the
Mitutoyo MSI release label ("6.213") that bay-config.csv uses. The
uninstall entry's DisplayVersion is empty. So bay-config.csv stays
canonical for the per-asset marketing version; exe FileVersion is a
concrete cross-check.
Backup rewrites:
- Replace the previous one-shot version detection with evidence reading:
bay-config.csv (asset->version+model), Formtracepak.exe VersionInfo,
device-map\DeviceName. The over-broad uninstall-reg regex is gone.
- Normalize DeviceName ("FORMTRACER Avant" / "CV-4500" / "CV-3200" /
"Contracer" / "Surftest") to bay-config notation (AVANT / CV-4500 / ...).
- Emit BayConfigMatch flag - true when bay-config-predicted model agrees
with the device-map\DeviceName on disk. False = drift, tech rechecks
before restoring to a new bay.
- manifest.json now stamps: AssetNumber, FormtracepakVersion, Model,
BayConfigVersion, BayConfigModel, BayConfigSource, InstalledExeVersion,
InstalledExePath, InstalledDeviceName, InstalledModelNormalized,
BayConfigMatch.
HKEY_USERS sweep:
- Wax/Trace bays log in as a per-site user (lg782713sd at WJ today,
ShopFloor post-SFLD-2.0, other accounts at other sites). The previous
HKCU:\ scan only captured the script's running user. Sweep every
loaded HKEY_USERS hive whose SID matches S-1-5-21-* (real user SIDs)
for Software\Mitutoyo / FORMTRACEPAK / FORMPAK / SURFPAK subkeys,
add them to $RegistryRoots. Username-agnostic - works at any site
without changes.
reg.exe export now also accepts the Registry::HKEY_USERS\<sid>\... PSPath
form by stripping the "Registry::" prefix when building the reg.exe
argument (previously emitted "Invalid key name" errors on HKEY_USERS roots).
Smoke tested against a real v6.213 / FORMTRACER Avant install on win11
VM: bay-config lookup matches, exe FileVersion read, device-map
normalized to AVANT, all four .reg files (HKLM, HKLM-WOW6432Node, HKCU,
HKEY_USERS\<interactive-sid>) exported clean, 0 errors.
Restore-side SID translation (HKEY_USERS\<src-sid>\... -> target user's
SID or HKCU on the new bay) is a follow-up. HKLM tree carries the
critical device-map\DeviceName, controller config, and machine settings;
the HKEY_USERS hive captures per-user UI prefs only.
