TT805 error. Desktop installation -

[mkswallow]

TurboTax Canada 2024 was working fine yesterday.

Today, on trying to start TT, I get TurboTax is unable to determine if an update is available.
TT805

Followed by "An unexpected error occurred while activating the product.

On pushing 'Activate Outside', I get "An unexpected error occurred while activating the product." again and TT closes.

I have tried re-installing but no change.

After phoning support, it became clear that after many years of both Kaspersky and TurboTax working on my desktop, they could no longer play together and Kaspersky had to go.
