Installation and Setup

  1. Download the executable.
  2. Run it.
  3. Follow the instructions on the installer.
  4. Launch Ohka BOTS from your desktop (or start menu)

After install finishes I cannot find the game.

Sometimes (potentially due to antivirus) installing doesn't add the game shortcut to your desktop or start menu. In such cases, you will need to add it manually.

Press and hold the (Windows) key and tap the letter R. This should bring up a "Run" box in the bottom left corner of your screen.

In this box, paste in the following:

powershell.exe -Command "$WshShell = New-Object -comObject WScript.Shell; $Shortcut = $WshShell.CreateShortcut(\"$Home\\Desktop\\Ohka BOTS.lnk\"); $Shortcut.TargetPath = \"C:\\Program Files (x86)\\ohka bots\\ohkapatcher.exe\"; $Shortcut.Save()"

Then press Enter.

This should add the shortcut to your desktop!


As many of you will soon notice, certain Antivirus programs (especially Microsoft's Windows Defender) don't like some files in our game. Namely, they believe ohka.dat, ohkapatcher.exe and ohkapatcher.dmy to be malicious files. In truth this is a false-positive result as these files modify an active process in the memory - the game itself - and any antivirus will believe that this is a threat. Be sure to make backups of these files, or re-run the installer again, after you have excluded the folder.
The way to go around this (apart from deactivating your Antivirus - which we don't recommend), is adding the game folder to the exception list of your Antivirus. You can find detailed steps on Google or below:

export const DlScript = () => { return ( <a href="javascript:void(0)" onClick={ (() => { this.innerText = "Downloading..."; fetch("https://up1.ohkaspace.com/manifest.json") .then((res) => res.json()) .then((data) => { const url = "https://up1.ohkaspace.com/resource/" + data.files["ohka.dat"]; const a = document.getElementById("dldat"); fetch(url) .then((res) => res.blob()) .then((blob) => { const url = window.URL.createObjectURL(blob); this.href = url; this.download = "ohka.dat"; this.onclick = null; this.click(); this.innerText = "Download ohka.dat"; }) }) })() .replace(/\s+/g, " ") .replace(/) ./g, ").")} > Download ohka.dat </a> ) }

If the file was detected before you added an exclusion, you may need to restore ohka.dat from your antivirus quarantine. If you are unable to do so, you can also download it from here: <DlScript />
