I’ve checked the Graphic card driver already and it’s latest what Asus provides.
What other info will you need to help me out?

Looking through the log it looks like your laptop barely meets the minimum requirement for Zwift: What You Need To Ride

If this a work computer?

Are you using a VPN or Proxy?

Are you an administrator on the laptop?

Have you tried right-clicking on the Zwift and running it as administrator?

Dear Paul,

Thank you for swift reply.

Yes it meets minimum requirements. Proc is i7, 4GB ram and Intel HD 4000 graphic card.
It works fine, currently I do not use VPN or proxy and yes I have tried to Run as Admin.

You could try completely uninstalling Zwift and deleting all the files/folders in Documents\Zwift and re-downloading and reinstalling.

Have you used Zwift on this laptop before?

Yes I did few times.

What bothers me in Log files:
[20:43:13 2019-10-18] Launcher: prefs.xml file found.
[20:43:13 2019-10-18] Launcher: prefs.xml file was found to have an error. Invalidating prefs.xml.

and
[20:43:11] Streamer: ERROR: #15 Loading XML file “C:\Users\nat\Documents\Zwift\Zwift_StreamingFiles_ver_cur.xml”!

[20:43:11] Streamer: ERROR: #15 Loading XML file “C:\Users\nat\Documents\Zwift\Zwift_StreamingFiles_ver_cur.xml”!

[20:43:11] Streamer: ERROR: #15 Loading XML file “C:\Users\nat\Documents\Zwift\Zwift_StreamingFiles_ver_cur.xml”!

I even tried to create these two .xml but it didn’t help.

Any more suggestions?

When you uninstalled and re-installed did you delete ALL files and folders in \Documents\Zwift

All important data is stored on Zwift’s servers.

No, I didn’t.

I have NO data yet. I can register a new acc if needed.
Yes I deleted everything.

Are you sure, on the Zwift Companion App it shows you have ridden 20miles/1hr37min.

Have you check Intel’s website to see if there is a driver update for the HD Graphics 4000?

Yes I have ridden some probably with phone app, I don’t remember well, it was a year ago.

Yes as I said I have checked for the latest driver: intel can’t override Asus vendor driver and the one I have is the latest available.

My driver version is 9.17.10.2884

No idea what that means, but I would still check the Intel site for the newest driver. ASUS might not have the latest driver for that graphics card.

Is this a work computer?

This is from Intel’s site: Support for Intel® Graphics

https://www.asus.com/2-in-1-PCs/ASUS_Transformer_Book_TX300/HelpDesk_Download/

When I try to install a driver from Intel it says it can’t override vendor’s driver.

Nah it’s all mine :slight_smile:

I can’t make more replies, there is a limit for new users.

I was able to install a driver from Intel. The one for win8 64bit didn’t work so I tried 8.1 and it was installed successfully but there is still an error. Still the same crash on start up.

Try doing this and see if it helps:

Documents/Zwift/prefs.xml file and changed the FULLSCREEN field from “1” to “0”:

<CONFIG>
        <SHOWGROUPMSGS>1</SHOWGROUPMSGS>
        <FULLSCREEN>0</FULLSCREEN>

There is no such a file, it was never created. As you may see in the log file.
Manual creating doesn’t help.
Any more ideas?

Any chance you can upgrade to Win10?
