Thought about extending in to a 4 seasons simulator. Could possibly have: Snow Heat Wind Anyway lets get a bit wet. Just kidding. I recompile your-program on win8versionx32, but I found other error. Please help me? Code: [Select]componentreg.pas(29,14) Error: Cannot find Laz_AVL_Tree used by ComponentReg. How to fix? Note: Duplicate unit "componentreg" in "BuildIntf 1.0", ppu="D:\lazaru s\components\buildintf\units\i386-win32\componentreg.ppu", source="D:\lazarus\components\buildintf\componentreg.pas" [code] ---------------------------------------------------------------------- Boleeman · 2025-04-23 12:57 A Possible Fix: In my project there is only component (the TTrackbar which is used to vary values). Perhaps delete the TTrackbar  and then create another one (and put in the previous code). I made my version using Lazarus Ver 2.2.4  32 bit compile , on Win 10 . I once had a problem with some Lazarus code made on Linux and found if I replaced the components on the form then everything worked and compiled OK. Also: That error seems to suggest that you installed some component twice, and then deleted it.
