Hi,
I didn't use WPI.
But You may try this code.! It may be helpfull.

Under cancelbutton click section You need to add this.

procedure CancelButtonClick(CurPageID: Integer; var Cancel, Confirm: Boolean);
var
ResultCode: Integer;
begin
SuspendProc;
Confirm:=False;
if ShowCancelBox = mrYes then
Cancel:=True
else
Cancel:=False;
if Cancel then
InstallLabel4.Caption:='Rolling back changes...';
if CurPageID=wpInstalling then
begin
if Cancel then
begin
ISDoneError:=True;
ISDoneCancel:=1;
WizardForm.CancelButton.Enabled:=False;
ButtonSetEnabled(NextBtn,False);
Exec(ExpandConstant('{sys}\taskkill.exe'), ' /F /IM pZLib.exe', '', SW_HIDE, ewWaitUntilTerminated, ResultCode);
DelTree(ExpandConstant('{app}'), True, True, True);
end;
end;
ResumeProc;
end;
