Properties DoubleBuffered and ParentDoubleBuffered was added recently, they are not yet in Lazarus 2.0.
Lazarus gives some dialog with "Ignore and continue loading" (for projects).

You can use Lazarus trunk or fix package manually.
Lazarus 2.1.0 r61214:62238 FPC 3.3.1 r40507 x86_64-linux-qt Chakra, Qt 4.8.7/5.13.2, Plasma 5.17.3
Lazarus 1.8.2 r57369 FPC 3.0.4 i386-win32-win32/win64 Wine 3.21

Try Eye-Candy Controls: https://sourceforge.net/projects/eccontrols/files/

I am using the Lazarus 2.0 Release (not fixes, not trunk). Both DoubleBuffered and ParentDoubleBuffered are present in LCL in the release.

From where did you get this version of UserControl? The one which can be installed by the Online-Package-Manger compiles and installs fine without any error messages. I tested Laz trunk and Laz 2.0.2 on Win 10.

from this address "https://github.com/jbsolucoes/ucp/" but with the version of lazarus 2.0.0 without problems worked. When updating the lazarus to 2.0.2 the problem appeared. Thank you for your contribution

Now I tried also this link, and it is working correctly too. So, I don't know what's wrong...

Did you try a clean rebuild of the IDE? "Tools" > "Configure Build IDE" > "Clean up": check "Clean all" and "Switch after building to automatically" > "Build".

I re-installed everything again the user control and where it gives the error is:
"The component editor of the class 'TUCControlsEditor' has created the error:" Error reading BtOK.DoubleBuffered: Unknown property: "DoubleBuffered"
This is when adding the TUCControls component.
Thanks
