Invitation code not found

I gotta mail from ratio. There is no any code. While accesing desktop ratio. Need a permission with code. Whether it not available in mail. Kindly help me to resolve it.

Invitation code isn’t required to install Ratio from now . In the email you should have got the link to download Blloc services. Install Blloc services and then through that app you will be able to install Ratio. To enable permissions for a few features go to permissions manager in Ratio Settings and it will guide you to download a desk tool . Download that desk tool (not Blloc Desk) on your PC and then follow the instructions in it to enable to permissions.
Hope this helps !!!
