@TurboTaxKim I managed to install it on my laptop and finished my taxes. One clue you might want to look into: On my desktop, for the 2017 taxes, it installed, but had an issue downloading my t5008 and t5 from CRA. I didn't have this issue with the 2018 install on my laptop. The software installed, AND was able to communicate with the CRA site as well. On my desktop, I have Avast. I tried disabling Avast to install the 2018 tax program and it made no difference.
