If you first time to use it:

function ISArcExtract(CurComponent:Cardinal; PctOfTotal:double; InName, OutPath, ExtractedPath: AnsiString; DeleteInFile:boolean; Password, CfgFile, WorkPath: AnsiString; ExtractPCF: boolean ):boolean; external 'ISArcExtract@files:ISDone.dll stdcall delayload';

then here's of example:

if not ISArcExtract(0, 50, ExpandConstant('{src}\Data1.arc'), ExpandConstant('{app}'), '', false, '', ExpandConstant('{tmp}\arc.ini'), ExpandConstant('{app}'), False) then break;
