Not installing on any blender versions

[kebab03]

I tried to install on blender 2.90- 2.91 - 3.0 - 3.3 . 3.5 in each version I get mod = import(module_name) ModuleNotFoundError: No module named 'blenderbezierutils_2' for blenderbezierutils28.py file While I get File "C:\Program Files\Blender Foundation\Blender 2.91\2.91\scripts\modules\addon_utils.py", line 382, in enable mod.register() File "C:\Users\Sharif\AppData\Roaming\Blender Foundation\Blender\2.91\scripts\addons\blenderbezierutils.py", line 10835, in register BezierUtilsPanel.colorCurves(add = True) File "C:\Users\Sharif\AppData\Roaming\Blender Foundation\Blender\2.91\scripts\addons\blenderbezierutils.py", line 2798, in colorCurves BezierUtilsPanel.shader = gpu.shader.from_builtin('FLAT_COLOR') ValueError: unknown type literal: 'FLAT_COLOR' for blenderbezierutils.py.

If you are trying on 3.5, I suggest you install the blenderbezierutils.py, not the 2.8 one. About the FLAT_COLOR issue, open the addon file, and find and replace all the "FLAT_COLOR" to "3D_FLAT_COLOR".
