If the missing file privileges problem persists, you may have to end the task each time you install/update a game. The igf圎M Module can interfere with permissions and prevent the user from reading/writing specific files, including those in the Steam directory. The following fix may work if you are using a motherboard with an Intel chipset and onboard graphics. Boot up Steam and launch the install/update.If it does, bump up the time to the full length of the installation/upgrade. Try starting with 10 minutes and triggering an install/update to check if it fixes the problem.Select a time frame for disabling the antivirus among the listed options.In the system tray, right-click on the Avast icon and hover over ‘’Avast shields control’’.In an overcautious effort to protect, antivirus software can interfere with write permissions in the Steam directory, causing the missing file privileges error, in which case we need to disable the antivirus for the length of the install or update.ĭue to their being many antivirus apps out there, we are focusing on Avast to provide an example. Click on ‘’Downloads’’ in the left-hand list.Click on ‘’View’’ among the options running horizontally along the top of the client window.Tick the ‘’Run this program as an administrator’’ option.Īnother easy fix is to clear out the temporary download cache Steam uses when obtaining game files from its servers.Select ‘’Properties,’’ then the ‘’Compatibility’’ tab.In the directory, right-click on the Steam.exe file.Search for the Steam directory (C:Program Files (x86)Steam in most cases).Right-click on the Windows Start menu, then click on ”Search.”.Try launching the install/download to verify if the error recurs.From the contextual list that drops down, select ‘’Run as administrator.’’.Right-click on the Steam client icon on the desktop or Taskbar, depending on how your system is set up.Close down Steam by right-clicking on the Taskbar, selecting ‘’Task Manager,’’ then click on the process called Steam Client Bootstrapper and hit ‘’End Task.’’.To bypass this, run the Steam client as an admin. In essence, permissions limited to read won’t allow Steam to write new data (game/update files). In many cases, the error may stem from read/write permissions on the Steam directory that differ depending on the user/group using the PC.
