Hi everyone,

I’ve noticed some odd behavior in SketchUp 2026.
If I delete the folder of any Fredo6 plugin — for example, Fredo6_VisuHole — from the SketchUp Plugins directory in Roaming (only the folder, not the main RB/executable file), SketchUp throws the following error on startup:

“Installation of Fredo6_VisuHole is probably incorrect. Subfolder is missing.”

What’s strange is that LOTT and Vignette still work fine after this. It doesn’t matter which Fredo6 plugin folder I remove — the same thing happens.

When I restore the deleted folder, SketchUp starts normally again, but then the behavior becomes the same as what Ramzix described earlier.
