If you want (as an admin) to grant tenant-wide consent for KONNEKT please visit here
KONNEKT setup requires local admin permissions
You can install KONNEKT by running the MSI file interactively. The setup dialog will start:
Accept the license terms and click next.
You may then enter your license key.
If you do not enter a license key, you start a 14 days trial version.
KONNEKT is now ready to start the setup.
Click Finish to finalize the setup.
After the installation is successfully finished, a pop up window shows up automatically to connect your Office 365 account and grant the required permissions to create an Enterprise Application in your tenant (see screenshots below).
To grant the permissions, you have to log in with an admin account or an account that has permissions to create an Enterprise Application in your tenant.
If you want a silent installation without any user interface interaction you can use the following command after downloading the msi installation file from here and rename it to konnekt:
msiexec /quiet /qn /norestart /i konnekt.msi LICENSE_KEY=<YourKey>
Instead of the <YourKey> in the end, enter your license key.
