Common Installation Steam Error Codes

Here we will detail out on all the incomplete installation error codes faced by Steam users. Moreover, we will also list the causes as well as the fixes that you can perform in order to solve the issue. We urge you to stick to the guide and follow accordingly, as missing any step can be harmful to your system. That’s all. Let’s get started.

Incomplete Installation – Error #2

This issue arises due to a conflict between Steam and a certain type of FAT32 Hard Drives. Steam had rolled out a fix update in response to this, but this issue still seems prevalent for many users.

Few users of the Steam community have reported that the problem can be rectified once the Steam Installation folder is shifted to default C-Drive location. Here’s all you need to know on how to move the folder:

Advertisements
  1. Close the current Steam application
  2. Explore the Steam installation folder until you find the Steam installation that needs to be moved
  3. Apart from these 3 folders, Steam.exe, Userdata, and SteamApps, delete all other files.
  4. Then paste them all into the default location in C-Drive.
  5. Run Steam

Now that the Steam location is changed, the default installation location also needs to be moved too. This is a must for players who’ll be required to download new games later on. Here’s all you need to know on how to correct the installation location:

  1. Open the Steam application
  2. Navigate into the Menu > Settings
  3. Go to the Content Libraries section and select Steam Library Folders
  4. The details of the current installation location will be visible here. Select Add Library Folder to make a new location path.
  5. Set the newly created location as default by right-clicking on it.

This should solve the Incomplete Installation Error #2 code. If the problem still arises, please get in touch with the Official Steam Support team.

Incomplete Installation – Error #3

This error occurs when Steam does not have a live internet connection. To find out the exact cause for this, try the following:

  1. Investigate Steam server status to check if Steam has not been shut down globally
  2. Make sure the problem is not related to the wifi router
  3. Check Firewall settings that may prevent Steam from connecting.
  4. Check for interfering programs and disable them
  5. Run a PC check for malware applications

  1. Investigate Steam server status to check if Steam has not been shut down globally.
  2. Make sure the problem is not related to the WiFi router.
  3. Check Firewall settings that may prevent Steam from connecting.

Incomplete Installation – Error #20

This error occurs when the Steam servers cant be reached. There are only two causes for this:

  1. Steam servers are under maintenance, or there are technical difficulties.
  2. Steam can’t be mapped to your network. Please check your port connections and firewall settings as well.

Incomplete Installation – Error #35

This error happens when Steam is not able to identify the ports on the router that are vital for connection with the servers. These ports are usually kept ‘open’ and should work if they have not been tampered with.

Please check your port connections and ensure they are kept open. Here’s all you need to know on the correct ports needed:

  • For Logging into Steam and Download:
    1. HTTP (TCP port 80) and HTTPS(443)
