Gpay POS installation guide

1What you need

2Downloading the installer

• Installer for stores (live): https://ai-gpayments.com/apkexe/AigpaymentsSetup.exe
• If your browser shows a warning that the file is “not commonly downloaded”, select 유지 Keep. Check that the file name is AigpaymentsSetup.exe.

3Installation

1. Double-click the downloaded file to run it. If POS is running, quit it first (the installer asks you to quit it).
2. Follow the on-screen instructions and click 다음 Next, then 설치 Install. Administrator rights are not required. The program is installed in your user folder (This PC › Users › (user name) › AppData › Local › Programs › GPayPos), so automatic updates also work without permission problems.
3. When installation finishes, a G-PAYMENTS POS shortcut is created on your desktop. If you select “Run now”, the program launches right after installation.
4. On a PC without the screen engine (WebView2), you are asked on first launch whether to install it. Click 예 Yes to install it automatically (internet required).

4First launch

1. Launch the program from the shortcut. On first launch, the latest version and the screen files are downloaded automatically (if there is a newer version than the installer, it updates automatically). If the message “A new version has been downloaded — click 'Restart now' to apply it” appears above the login screen, click 지금 다시 켜기 Restart now. If both the program and the screens are new versions, after the restart the message “Click 'Restart now' one more time and you are done” appears, so click one more time. While this message is displayed, the login button is locked.
2. On the login screen, select [POS] and enter your store ID and password. If you turn on “Remember ID”, your ID is filled in automatically from the next time.
3. Check that the very bottom of the login screen shows the program version · screen version · “운영” (live). If it does not say “운영”, reinstall with the installer for stores (live).
4. When the table screen appears, check that “Receiving orders” (green) is shown at the top left. Installation ends here.
5. Next, the “First-time setup” prompt appears. Set up the receipt printer → cash drawer → kitchen order slip → POS screen, in that order. To set up later, click 나중에 Later; to see it again, click Settings > 처음 설정 안내 First-time setup guide.

5Initial setup steps

The “First-time setup” prompt shown on first launch guides you through items 1 to 4 in order. You set up the remaining items once on the settings screen. The details are covered in the same order in Chapter 1 “Initial setup” of the user manual.

Receipt printer: 프린터 고르기 Choose printer → choose the connection method (Windows printer, Select USB printer directly, Connect by LAN · IP, Connect by serial · COM, or No printer) → paper width → 시험 인쇄 Test print.

6Reinstalling · replacing a PC · uninstalling

• Reinstalling: Run the same installer again. The store settings file (gpaypos.ini: printer, cash drawer opening method, staff PIN, and so on) is kept and not overwritten. It is not changed by updates either. The table layout is stored separately in a user folder outside the installation folder, so it remains even if you reinstall or uninstall.
• Replacing a PC: After installing on the new PC, copy gpaypos.ini from the installation folder of the old PC to the same location on the new PC, and your settings are transferred. The printer is a different device, so select it again on the new PC. The table layout is not in this file. Either rearrange the tables on the new PC at Settings > Table layout, or copy the layout-(store number).json file in the This PC › Users › (user name) › AppData › Local › GPayPos folder of the old PC to the same folder on the new PC. The permission to cancel paid orders is stored on the server, so you do not need to move it separately.
• Uninstalling: Remove G-PAYMENTS POS in Windows “Apps & features”. The settings file stays, so it is used as is if you install again. To delete the settings too, delete gpaypos.ini in the installation folder.
• Updates are automatic. Each time you launch it, the program checks for a new version and downloads it, and when the message appears, click 지금 다시 켜기 Restart now to apply it (for a version where the program and screens changed together, the message may appear one more time, so click one more time). You do not need to reinstall. Manual 1.12

7No-install version · Windows 7 and 8

• No-install version (zip): Extract the zip to any folder and run gpaypos2.exe. It has the same contents as the installed version; only the way of installing differs. It is for special environments, and the installed version is recommended for stores.
• Windows 7 and 8: Get the zip that includes the screen engine (WebView2) installer from the person in charge, install the screen engine first, and then run the program.
• The “entry point not found” problem on Windows 7: Program versions 1.3.188 and earlier did not start on Windows 7 and showed a window saying “The procedure entry point GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll” (this was because they used a feature that exists only in Windows 8 and later). From 1.3.189 on, this cause has been removed. Check that the version at the bottom of the login screen is 1.3.189 or later. Windows 7 is an environment for which Microsoft support has ended, so there may be other limitations, such as the screen engine (WebView2) version.
