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

The .iso should contain it all.

You could just use Windows Update under Control Panel too.

This is all written in the starting post.

i need to download it all right? not only the .iso?

Zoldyek you first need to launch windows updater (start -- windows update) and download necessary updates including the latest windows updater tool and a small SP1 update then you go and download the big SP1 .iso from the links provided by teutep

[ZOLDEYK]

first i would like to thank, Teutep, who have a lot of patience teaching me, and mahmoud for this really helpful thread, i would like to share how i manage to work for future people who need this.

First i download this one. https://www.microsoft.com/en-US/download/details.aspx?id=5842
( ONLY the .iso file is needed its like 3.2 GB )

Second i download this after i finish installing the first one
https://www.microsoft.com/en-us/download/details.aspx?id=49093

Big thanks to you, bro. It's working perfectly now.

You're welcome Xsasternh.

Do I need to reinstall Steam?

This doesn't work on new i7 7700 processors because microsoft stopped support for Windows 7 on these systems.

So if your processor is too new you can't install that update nor can you install it via automatic updates:

https://support.microsoft.com/en-us/help/4012982/the-processor-is-not-supported-together-with-the-windows-version-that

Unless steam fixes it people with a new system who have that error cannot access anything else than their game library because everything else won't work. Steamwebhelper cannot be started because of this.

Hey man, have you already fixed that? My windows update is not working, someone here talked about some DISM tool. Then I struggled a bit but found a ♥♥♥ version of this tool here.

http://www.majorgeeks.com/files/details/dism.html

Be careful, the download mirrors are under "Download locations" in yellow letters. There are 29872987 download buttons on that site.

Also you will need the Microsoft update from here.

https://www.microsoft.com/en-us/download/details.aspx?id=49093

Ok you don't even need to unpack DISM, you can run the exe from inside the .rar, x86 or x64 depending on your PC, probably x64. There is an "update" tab or something like that on the left, mine is in portuguese so I don't know the english word you will find there. Then from there you will be able to search that Microsoft uptade that you have downloaded. There will be a small green bar at top left of DISM screen showing the install progress.

This DISM tool forces the installation of the updates, it worked here.

God grant you health you good man
i just install this windows update and all works now

[Play Doggy]

Thank you all))) Finally I solved the problem. I first tried to install the update on Windows KB976932 but I already have. I then installed the update KB2999226 and all started to work). Before these updates I was cleaning cache, cookies and so on in the steam client and it did not help. And now everything is OK)

I'm using the windows update tool. hopefully this would solve the problem

[XclusivVv]

IF you can access the STEAM STORE from a normal web browser, but can't access it from inside the Steam Client, then download this:

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

that should fix it.

Note: If you've disabled Windows Update you will need to Enable it and Start the Windows Update service before trying to apply that update. Once you've applied the update, you can disable Windows Update again.

no, KB2999226 is the last file you need to install.
for win7 you need this package for sp1
http://www.microsoft.com/downloads/details.aspx?familyid=cdd5866a-43b3-409e-8fd7-e37b0a9ccc63
and yes take the .iso file

my hero, you saved my life, i could kiss you

а теперь посмотри на ник твоего "героя"))

[Varainger]

Just like the OP suggested, but want to confirm:

For Windows 7

- Search the dll file on C: drive
- If you are lucky you have it there somewhere. I did.
- Copy it into the Steam/bin/cef/cef.Win7 folder.

-> Client works again.

No need as far as i can see to install the kb update.

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.

hey man, i cant update anything (i have win7 64bits too) but it says when i run the thingy i downlaod from the page, it says "update is not applicable to this pc" (paraphrasing here, it's in spanish) any idea why?

You might turn on windows update temporary

Yea so for those who've had issues with steam client only, the solution is above.
What worked for me was the missing .dll file (API-MS-Win-core-file-l2-1-0) I guess it's a new file now that steam client needs in order to load things up.
You can download it on the internet.

So thanks steam support and thank you guys for the instructions.
