Atlassian SDK Installer ignores installation directory

We wanted to do a silent installation with the SDK Installer with the following command: “sdk-installer-8.2.7.exe -varfile response.varfile -q”.
The installer ignores the installation directory parameter in the response.varfile.

Can someone please tell us what the problem is and how we can fix it?

Thanks for the help in advance.

Best regards,
Katrin
