Install
Download Setup.exe from the download page and run it. The installer puts Apex Solver in your Windows user profile, adds a Start menu entry and opens the app. You do not need admin rights.
Activate
On first start the activation dialog asks for your license key. Paste the key from your purchase email, for example APEX-XXXXX-XXXXX-XXXXX-XXXXX. Dashes and letter case do not matter.
Activation needs an internet connection once. After that the app verifies the license on your computer and checks in with the license server at least every 14 days. If a check cannot reach the server, everything keeps working for 7 more days. After that the app still opens, but solving and export wait until the check succeeds.
Open or build a tree
Use Open tree in the toolbar to load a saved tree, or New to start one. Recent trees are under Recent. To build a postflop tree, go to the Postflop Tree Building and Calculations tab and set the board, pot, stacks and bet sizes. Tree Information shows the settings of the tree that is open.
Solve
Set Accuracy in the toolbar. It is the target exploitability as a percentage of the pot: smaller numbers take longer and get closer to equilibrium. Press Go to start and Stop to end early. The toolbar shows the current iteration and exploitability while it runs.
Read the results
The Browser tab is where you study. The top row shows who acts at the current node and how the range splits across actions. The line panel on the left lets you step through the tree.
- Grid views. Strategy, Strategy + EV, Range, Equity, EV and Blockers. More options are under More and Display.
- Layouts. One grid, OOP | IP side by side, or Compare.
- Hand detail. Click a cell to see each combo with its action mix, equity and EV.
- Range explorer. Equity buckets for both players, suit filters and a graph view.
Move to another computer
Each license covers a set number of computers. To move, deactivate the old computer from inside the app or on the account page, then activate on the new one. If the old computer is gone, the account page can still free its seat.
Updates
Apex Solver looks for updates when it starts and when you check from the app menu. Updates download in the background and the app asks before restarting. Updates are offered for releases inside your license's update period. With a perpetual license, builds from that period keep working afterwards.
A build released after your update period ends will not solve or export with your license, even if you install it by hand. If the app says your updates have expired, the account page offers the newest build your license covers. Release notes for every version are in the changelog.
