No specific info about version 4.1. Please visit the main page of CostMin on Software Informer.
I am associated professor in mechanical engineering department.
Do not download it, it took me 4 hours straight to fish out all the junk from this software.
Please tell me how to uninstall the software.
I only know how to get it out of Chrome:
1) uninstall all unrecognized software (be careful about this)
2) got to extensions, and check the developer mode box
3) find the ID for CostMin
4) go to C:\Users\(your user profile)\AppData\Local\Google\Chrome\User Data\Default\Extensions
5) delete the folder labeled with the CostMin ID
CostMin is gone! And you can get on with your life.
