The Issue Sierra Chart (x64 version) would not open inside Windows 11 ARM on a Mac running Parallels. The process showed in Task Manager, but no window appeared. The ARM version opened fine, but the x64 version was required for custom studies. Root Cause You were correct John thank you Windows 11 ARM emulates x64 apps. Sierra Chart is incompatible with one of the newer ARM CPU emulation features, causing it to start invisibly with no UI. The Fix 1. Enable the ARM compatibility option: - Right-click SierraChart_64.exe → Properties → Compatibility → Change emulation settings - Turn on: “Hide newer emulated CPU features (x64 apps only)” 2. Run Sierra as Administrator: - Right-click SierraChart_64.exe → Properties → Compatibility - Enable: “Run this program as an administrator” Optional Step Use Sierra’s “Reset Windows” feature once it opens to avoid future off-screen window issues. Result After applying both settings, Sierra Chart x64 launches correctly with all chartbooks working. |
