In a statement to the ASX this morning, Solution 6 said Tyler and the board of the company had "mutually agreed that in the light of recent events it is now in the best interest of shareholders" for Tyler to resign.
Solution 6's chief operating officer, Lindsay Yelland, has been appointed as acting CEO and MD.
The appointment follows Tyler's ridiculing last week of industry rumours that Yelland would be offered the top job.
Last week Tyler confronted publicly for the first time reports of drug charge allegations, failed business ventures and unfulfilled promises to shareholders.
It is not yet known whether Tyler will retain his 10 per cent option in the company, valued at close to $50 million.
