Error launching the Editor: No Permissions to execute the application path

Unity Engine
1

Hello Guys,

today i wanted to open a 2017.4.6f project so i installed it via Download Archive
with the unity hub. Sadly im neither able to start my project, nor im able to create a new project with the version 2017.4.6.

Everytime im trying to do so - this error appears:

Error in launching the editor: You do not have the permissions to execute the application path: C:\program files\unity\hub\editor\2017.4.6f1\editor\unity.exe.
Even the other versions are also installed this way.

I already looked up for the permissions of the folder/Exe but i do have them.

I can still use all other versions - only the 2017.4.6 isnt working for me. I already de - and reinstalled it, but i didnt work out for me.

Do you have any tipps?

Can you try Run As/Administrator for unity.exe ? Right click, etc.

Ive already tried it, but i doesnt work out. Im getting a similar error saying:

“Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item.”
