Can't access community and store from steam client.

[Mahmoud]

It works with mobile and browser though. I am also able to perform in-game purchases.
I did a new steam client installation but the problem persists.
HELP

EDIT: this is a problem with SteamWebHelper not launching because of missing .dll files.
For windows users:
1 - Launch windows update tool and download necessary updates including service pack1
2 - Install full SP1 from here (use the .iso package for an automatic installation)
http://www.microsoft.com/downloads/details.aspx?familyid=cdd5866a-43b3-409e-8fd7-e37b0a9ccc63
3 - update your .dll files
https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows
4 - restart steam.

Alternatively if you want to avoid all the telemetry stuff coming with the update package, you can downlod api-ms-win-core-file-l2-1-0.dll from somewhere (or copy/paste it from /system32 or /sysWOW64) and move it to Steam\bin\cef\cef.win(x)\
then uninstall the updates.
This might not work for all Windows versions

EDIT2: this has been fixed in the new steam client update 10/18/2017

Have you tried removing the cache under [Steam > Settings > Web Browser > Delete Web Browser Cache] ?

What happens when you try to access the community pages?

Black screen? If you hold LMB and move your mouse around, does it highlight any text?
Anything?

using it fine with mobile and browser
But with steam client it's just black screen with loading circle on top right going forever!
it doesn't highlight any text.
I got the steam news and deals when I restart the client but it's also a black screen.
Only the library works.

What's your firewall? Have you tried temporarily excluding SteamWebHelper within it?

It should be located under

C:\Program Files (x86)\Steam\bin\cef\cef.win(x)\

C:\Program Files (x86)\Steam\bin\cef\cef.win(x)\

starting it gives an error about a missing .dll
and it's not on the task manager
is it supposed to be working in the background ?

It's supposed to be running in your Task Manager.

At the time of posting this, I have 5 Steam Client WebHelper processes running.

so all of the sudden I got some missing .dll ?
I completely reinstalled steam (removed everything but steam.exe and steamapps) but nothing helped !
Could you upload that file plz ?

If you launch manually Steam\bin\cef\cef.win(x)\steamwebhelper.exe, you'll see that "api-ms-win-core-file-l2-1-0.dll" is missing.

Steamwebhelper used to need "api-ms-win-core-file-l1-1-0.dll", since 11 Oct 2017 update it needs "api-ms-win-core-file-l2-1-0.dll".

Update your runtime DLL here (take the version matching your system) :

https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows

(If after download the runtime installer doesn't work, activate, even temporarily, the "Windows Update" service).

Tested on Win7 64bits.

EDIT: IF YOU LACK THE WEBHELPER:
I'd suggest going through this list (possibly your antivirus interfering with it all)
https://support.steampowered.com/kb_article.php?ref=9828-SFLZ-9289

You could try going in Selective Startup and seeing whether all the files install properly upon launching Steam.

[Win] + [R] -> msconfig -> [Enter]

Under the [General] -tab

Startup selection

__	Normal startup Load all device drivers and services
__	Diagnostic startup Load basic devices and services only
	Selective startup Load system services __ Load startup items Use original boot configuration

Then go under [Services] -tab, and tick this box:

Hide all Microsoft services

Hit [Disable all] from the bottom right corner.

Reboot your computer. Now navigate yourself under

C:\Program Files (x86)\Steam\

Remove everything except

• Steam.exe
  
• steamapps -folder
  
• userdata -folder

Start up Steam and see if it loads the SteamWebHelper under Steam/bin/cef/cef.winx/ this time.

EDIT:

I just realized you had .dll issues launching it. I should drink today's coffee. Read the above response instead.
