Downloading and Installing via Microsoft Store 

1. Go to the Microsoft Store on your HoloLens Device and look for "AR 3S Pro".
2. Click on the "Get" button and, if you have not already done so, log in to your Microsoft account or click on "No, thanks".
3. Next, press on the button reading "Install on my devices" to install AR 3S Pro on your HoloLens.
4. The AR 3S Pro Client app should now be among your installed apps.

1. After this, a password is required, which you will receive only upon request - in this case, please contact our sales team via "sales@holo-light.com".    
3. Once you entered the correct password, click on "Download" and a ZIP folder will be downloaded to your PC.

Troubleshooting

• Does your PC meet the minimum Requirements specified here (especially regarding the graphics card)?
  
• Did you run the server app as an administrator?
  
  • If not, please right-click on the program and select "Run as Administrator".
• Is your Firewall blocking the application?
  
  • If so, please deactivate it and try again.
• Does your PC require a Windows Security Check?
  
  • If so, go to "Windows Security" -> "Virus & threat protection" -> "Scan Now" and choose either "Quick scan" or "Scan Options" -> "Custom Scan" and select the AR 3S Pro Server .exe file
• Did you start the  AR 3S Pro Server on your primary monitor (in case you're using multiple screens) ?
  
  • You can check which monitor is the primary screen at "Settings" -> "System" -> "Rearrange your displays" -> "Identify", the primary screen will now display the number "1".
    
  • This known issue has now been eliminated with AR 3S 1.4.0.0 and should no longer occur as of this version.
    
• Is your operating system (on the HoloLens 2 or your PC) set to a language other than English?
  
  • Languages such as French or Polish have caused problems in the past, but with AR 3S Pro v.1.4.0.0 this known issue should be eliminated. If in doubt, please update if you are using an older version.

If the startup issue still persists even though you have gone through the items above, please do not hesitate to contact our Support Team at support@holo-light.com.
