This error is typically fixed easily although in some cases, more advanced solutions may be needed. Learn what you can do below to fix this problem.

Causes of Steam Incomplete Installation error

You’ll have to check several factors if you want to fix this Steam error. These are the things that might cause the problem:

Steam server outage or maintenance.

When a game download is interrupted and Steam shows that the installation is incomplete, it may be due to a problem with Steam servers. This means that the cause is outside your control.

Any download or installation that you’ll do will most likely end up with a problem so all you need to do is wait until the issue is resolved.

Local network issue.

The other possible reason for this problem can come from your own local network. Your local network consists of your modem, router, computer and anything in between. When troubleshooting any Steam connectivity issues, checking for any possible local network issue must be performed.

Slow internet connection problem.

If your internet connection is slow or intermittent, Steam-related activities like online gaming, browsing, downloading/installation, or streaming may suffer.

The same can be said if you have low bandwidth allocation on your PC. This happens if your computer experiences slow connectivity issue because other devices in your network is hogging all the bandwidth. Devices that stream HD or ultra HD videos or download large files may be using all that bandwidth leaving your PC with little to nothing.

Firewall not set up correctly.

In some instances, Steam incomplete installation error may be attributed to incorrect firewall setup in your computer or network. If you are using Steam for the first time, your firewall may be preventing your PC from connecting to Steam network.

Interference from third party software.

Certain programs may block Steam and Valve games from being downloaded and installed. If you have a security software (antivirus, anti-spyware, etc.) installed, you should check if one of them is causing the Steam issue you’re having.

Malware

Some malicious software are designed to attack Steam or steal Steam credentials. If there’s such a malware in your machine, this may be the reason why Steam is crashing or not connecting properly.

Below are the telltale signs that you should be aware of to know if your PC is infected with a virus or malware that attacks Steam:

unrelated, random ads appear when Steam is launched or opened
browser opens and leads to an ad or website when clicking something on Steam
“Access Denied: You don’t have permission to access http://steamcommunity.com on this server.” error keeps popping up

If you experience any of these things in your PC, you may have a malware issue at hand.
