Replace per-type eDNC_6-4-5.msi with eDNC-6.4.7.msi (ProductVersion
6.4.7.0) in collections, nocollections, heattreat, and partmarker.
01-eDNC.ps1 already prefers the single shared installer at
C:\PreInstall\installers\dnc (6.4.7); aligning the per-type fallback
means an empty shared dir can no longer install a stale 6.4.5. All DNC
types now resolve to 6.4.7 on either path.
