Getting started

@AntonS1 Have you made sure that there's no security/anti-malware software blocking TurboTax Desktop? Ex: Windows Defender, Norton, McAfee etc... You may need to add TurboTax as an exception, or temporarily disable the software while you activate the program.  

You can also try to force TurboTax to retry online activation using the following steps;

1. Go to the path "C:\ProgramData\Intuit Canada\tt2018\"
2. Delete TTConfig.ini file
3. Launch TurboTax 2018
4. It will ask you to enter the License code - enter it and try to activate again.
