Well hello Tonymac community!
I tried to install for new Catalina version of os on my laptop Asus n56vz and got error:

“An error occurred validating the installer data. The download is either damaged or incomplete. Redownload the installer and try again.”

But before i added new ssd and commit guide for install clover and installmedia on the flash drive:


In this forum I did read recomendation for add to trash from Application folder source installer and load again from app store. I did it and got same error with nothing result.

If you have this issue how can to fix it?
What is may problem in this level ?

Thank you!
 
Are you installing from USB? Also update your profile with the laptop details.

Is there debug or logging system during process of installation ? That can be visible more extensible message about stop error ?
Thank you!
