I got the message that 5.7 had been installed successful.
When I tried to open the programm, I got the message that I didn't have the access rights for the element.
I uninstalled 5.7 and installed 5.0 again.I got the success message, tried to open the programm and got again the message that I don't have the access rights.
I was signed in as administrator.
What can I do?
What is the complete unedited word-for-word error message?
You don't have the proper permissions in your operating system. Most likely refers to your catalog file, but perhaps it's something else (my German isn't that good). Check to make sure the folder that contains your catalog file has WRITE permission.
