Add Eaglesoft Schick IOSS driver stack installer for ES 24.20+ workstations

[AlrightLad]

Summary

Automates the Schick sensor driver migration required for Eaglesoft 24.20+ (IOSS replaces the discontinued CDR driver integration per Patterson Answer 44313). Built for an ES 25 upgrade at a 30+ workstation dental office; eliminates the per-machine manual procedure.

Installs, per Patterson's documented sequence: Schick digital integration (registry import, Answer 18352) → MSXML 4.0 (skip-if-present) → CDR Elite 5.16 + Shared Files strip preserving CDRData.dll/OMEGADLL.dll + CDRPatch-2808.msi (produces CDRImageProcess.dll 5.15.1877.10093 for pre-24.20 image filters) → IOSS v3.2 (VC++ 2019 prereq, en-us MSI) → sets Sirona Intraoral Sensor Service to Automatic (Delayed Start) per Patterson guidance.

Design

• 100% non-interactive — RMM execution only; hard-fails with guidance if $env:RMM is not "1" rather than prompting. Deliberate deviation from the template's dual-mode pattern: an installer that silently strips the Schick driver stack should never run on ad-hoc manual invocation.
• Per-component B2 URLs (repo/vendors/Patterson-Eaglesoft/), empty URL = phase skipped — composable per workstation profile (full fresh install, IOSS-only top-up, filter-stack repair)
• Eaglesoft version gate: reads uninstall registry ("Patterson Eaglesoft", highest parseable version across multiple entries), hard-stops below 24.20 — prevents stripping the legacy CDR stack a pre-24.20 install still requires. SkipVersionCheck=1 override.
• Idempotent: IOSS service presence + CDRImageProcess.dll version + msxml4.dll checks skip completed components; safe to re-run fleet-wide
• Fail-fast: aborts before any changes if CdrEliteArgs is unset while the legacy stack is needed (CDR Elite Setup.exe is InstallShield; verified silent switches: /S /v/qn /v/norestart)
• Registry import filtered to Schick_Sensor_Integration.reg (package ships 14 vendors' files; importing all would enable integrations for absent hardware)
• Disables Core Isolation/HVCI per Patterson Answer 40785 (vendor requirement for sensor function; DisableCoreIsolation=0 opt-out)
• 64-bit relaunch guard, TLS 1.2, Start/Stop-Transcript with full phase logging

RMM Variables

IossUrl, CdrEliteUrl, DigitalIntegrationUrl, MsxmlUrl, CdrEliteArgs, Description + optional DigitalIntegrationRegFiles, DisableCoreIsolation, SkipVersionCheck, ForceReinstall (defaults in header)

Testing

• Piloted via NinjaOne on a Win11 Pro workstation (ES 24.20.03, unconverted legacy stack). All phases exit 0. Post-reboot verified: SironaUSBService Running / AUTO_START (DELAYED), CDRImageProcess.dll 5.15.1877.10093, CDRData.dll + OMEGADLL.dll present, IOSS 3.2.4024.52346 registered, HVCI 0.
• Version gate verified against real registry data (dual uninstall entries 24.00.07 + 24.20.03 → correctly selects 24.20.3).
• PSScriptAnalyzer clean except PSAvoidUsingWriteHost (repo convention for RMM output).
• Functional sensor gate (acquisition test, pre-upgrade exam filter rendering) pending on an operatory workstation before fleet rollout.

Known limitations

• IOSS does not function over RDS/RDP (vendor limitation, Answer 44313) — not applicable to this deployment, noted for reuse
• Module/sensor firmware updates remain hands-on via the IOSS Configuration Application
• Default static enhancement is a one-time office-wide GUI step, not scripted
