i have a problem. Actually i use wpi installer by razor, but in the instalation during extraction files, when i click to cancel the program closes but not delete the extracted files (only when appear some error). Also, when i use pzlib v3, the setup not closes the program, it keep running in task manager and the instalation not be canceled. How to fix this ?. I need to add some code to my scrip ? Thanks
