SketchUp 2026 + OpenStudio Plugin Compatibility Issue – Always asks to remove OS content on open

edit

Hi everyone,

I’m having a problem with SketchUp 2026 and the OpenStudio plugin on Windows 11. Every time I save an OpenStudio file in SketchUp and then re‑open it, I get a dialog saying it wants to “remove previously linked OpenStudio content” and only opens after removing it. Even if I open SketchUp first and then the file, the message still appears.

I have verified: • OpenStudio tools appear in SketchUp after startup (toolbars load) • But at file open time, the plugin does not load early enough and SketchUp doesn’t recognize the OS objects

I think this is a compatibility/loading timing issue between the plugin and SketchUp 2026.

Versions installed: • SketchUp 2026 • Latest OpenStudio Application (v1.11.0-rc2) + SketchUp plugin (v1.11.0-rc1)

Has anyone experienced this? Is there a known compatibility issue with SketchUp 2026? Is there a workaround or setting to ensure the plugin loads before the file opens?

Any guidance would be greatly appreciated.

Thanks!
