I'm using Delphi XE4 with the latest code for vcl-styles-utils at https://github.com/RRUZ/vcl-styles-utils. I can not compile my app and getting the following error:
[dcc32 Fatal Error] Vcl.Styles.Utils.ScreenTips.pas(57): F1026 File not found: 'Vcl.SysStyles.dcu'
I can not find this unit anywhere. Where can I find the Delphi unit Vcl.SysStyles ?
