Hello...trying to upgrade my Mac to Mojave. The installer in applications said was damaged and can't be used. I deleted the application and now need help to reinstall application?

Hello Community!

I am needing to upgrade my Mac from High Sierra to Mojave. In applications, I tried to install but got this error message.....this copy of the install application is damaged and can't be used. So I deleted the application, and need some help at this point to get Mojave installed on my Mac. Can anyone help with this? Thanks if possible
