Hi Sergey, thanks for replying!

>Do you have READ EVENTS in VFP EXE code?

No, I didn't, just put it (as below) but occurred the same error (maybe I didn't do it the right way...)

 Procedure TASKsched 
 
 Read Events
 
 Set Talk   Off
 Set Clear  Off
 Set Cursor Off

 Set SysMenu  Save
 Set SysMenu  To

 If ! Directory ("C:\Temp")
    MkDir C:\Temp
 endif

 Set Procedure To GenProcV         , ;
                  TaskProcs        , ;
                  TaskProcess      , ;
                  TaskStarter      , ;
                  TaskBackupRecover, ;
                  LibraryTASKsched

 . . .

Any other ideas?

Regards,

Fernando
