Install macOS Mojave application says it's damaged multiple times

I'm trying to install macOS Mojave but after I download the installation thing it says "This copy of the Install macOS Mojave.app application is damaged, and can't be used to install macOS."

I've tried deleting it from applications and redownloading it twice and it didn't work, I'm currently using high sierra.

iWorks compatibility with Catalina 10.15 Hello, Does anyone has the official install package for Pages, Numbers and Keynote 11.1 compatible with Catalina ? I have a problem on my Appstore account from which they disappeared after re-installing my computer from zero. The Apple Support can't help me with restoring them as i'm on a mid-2012 MacBook Pro. They told me i should find the official install package to have them back on my account. But the last version available on the Appstore for download is the v12, not compatible with Catalina. Thank you for your help, Sébastien

Downloading MacOS Ventura for a 2nd time. I am trying to download MacOS Ventura in my iMacBook Air 2020, but when I download it, it doesn't "apply the changes" and, when I open settings, it asks me to download it again, just as if I didn't download anything.

Ventura security problems. I updated to Ventura 13.1 . I can not find a way to run for example VMD, molden etc. These are the programs I used to work with on a daily basis. I am getting the errors: For VMD: “startup.command” cannot be opened because it is from an unidentified developer. macOS cannot verify that this app is free from malware. For molden: “libgfortran.3.dylib” can’t be opened because it was not downloaded from the App Store. Your security settings allow installation of only apps from the App Store. I did not find a way to make it work. Could anyone help, please? Is there any official way for system problems for mac users? This is really annoying to struggle with this kind of new features that does not work properly on the updated macOS. I have a feeling that with the every update I am less and less happy with the operating system and regret that abandoned linux enviroment... Thank you in advance for your help, tips and tricks.

ok, I fixed it. I made a copy of the "damaged" Install macOS Mojave.app application and then opened the copy and it worked.

I have no idea why that worked because the original copy was apparently damaged but it did.

I hope this might be of some use to people having the same problem.
