What

Admin installer: run all post-install and uninstall steps as the installing account (no runascurrentuser), so when deployed as SYSTEM (e.g. SCCM) every step can succeed and write to all-users / ProgramData.

File: release/pyrevit-admin.iss
Change: Remove runascurrentuser from all [Run] and [UninstallRun] entries (keep runhidden). Aligns with the per-user installer (pyrevit.iss), which uses only runhidden for these steps.

Why

Fixes #2923 — pyRevit installed via SCCM (Windows System account) should show as attached for all users.

Under SCCM the installer runs as SYSTEM; there is no interactive "current user." With runascurrentuser, every step (caches clear, detach, clones add, attach) could skip or run in a broken context. Running all steps as the installer (SYSTEM) ensures:

• clones add registers the master in ProgramData (all-users config).
• attach creates the .addin in the all-users Revit Addins folder so every user sees the pyRevit tab.
• Uninstall: caches clear and detach run as SYSTEM so SCCM uninstall cleans up correctly.

Verification

• SCCM / psexec -s: Run admin installer as SYSTEM. As a normal user run pyrevit attached — should list the attachment (master | AllUsers | path). Revit should show the pyRevit tab. Uninstall as SYSTEM; all-users .addin and caches should be cleaned.
• Interactive admin: Run admin installer as administrator. All steps run as admin; normal users should see the attachment.
• Per-user installer: Unchanged; no edits to release/pyrevit.iss.
