I am trying to update from El Capitan to High Sierra on my MacBook Pro Mid 2010. However, anytime I try to open High Sierra in the Appstore there is a message that the application is damaged and can´t be used to install macOS.
Have you any recommendations where to get a functional and safe copy of macOS High Sierra?
MacBook Pro 13″, OS X 10.11
However, anytime I try to open High Sierra in the Appstore there is a message that the application is damaged and can´t be used to install macOS.
That message, courtesy of the Department of Obfuscation, simply means the current installer found an older, outdated copy of itself already in your Applications folder and cannot proceed — yet.
Open your Applications folder, find the old installer and delete it. Then you should have no further issues with the update.

Thanks a lot! I was able to start the installation of High Sierra after deleting the old files. ^^
