Add Components but error with unit chmreader used by ChmLangRef

[folkeu08]

Hi team,
I want add component in Laarus 2.0.12 under Windows 10 64 bits.
I have an error like this:

Code: Pascal  [Select][+][-]

1. Création de l'EDI: Code de sortie 2 - Erreurs : 1 - Avertissements : 2
2. Warning: svn not in path.
3. Warning: Recompiling chmreader, checksum changed for E:\lazarus\components\sparta\generics\lib\x86_64-win64\generics.collections.ppu
4. chmreader.pas(81,12) Fatal: Can't find unit chmreader used by ChmLangRef
5.  

If only to uninstall "ChmHelpPkg 0.2" to allow the installation of additional components, how do you keep "ChmHelpPkg 0.2"
Otherwise, how do you associate a help file with the software ?
Thanks
François

In 2.0.12, there is a conflict between ChmHelpPkg and sparta_dockedformeditor (https://forum.lazarus.freepascal.org/index.php/topic,53474.msg395632.html). If you need ChmHelpPkg you must uninstall spart_dockedformeditor, but there is a new dockedformeditor (https://forum.lazarus.freepascal.org/index.php/topic,53474.msg395632.html#msg395632) which you could try instead.
