A. If you are getting this error message, please check below points:
Check if the setup file is meant for your version of Windows, Make sure you are using Windows 7 or above. If you are using Windows XP or Windows Vista, setup may not work.
Maybe the download was interrupted or got corrupted. Clear your browser cache and re-download the setup and see it it works.
Right-click on the .exe file, select Properties and then click on the Unblock button.
Disable your security software/antivirus temporarily and see if that helps.
If you saved the setup file on a Network, you may get to see this message. Save it to your local computer and run and see if it works.
Maybe Administrator rights are required. So then either log into an Administrator account or create a new Administrator account, log into the Administrator account and then run the Installer package.
