[Outdated] VAC Authentication Error Fixer - Page 5 - MPGH

Doesn't Valve have their own fix for this?

Thank you.

This suddenly does NOT work for me any longer. And yes i have set up everything correctly and even with restart and turn off firewall twice + deleting appcache folder everytime it still does not work and i get a mm ban ....

[My solution] VAC Authentication Error

[ - ] Warning
- These were the steps taken by myself.
- It can work, may also not work.
- Do not use cheats, to correctly verify that the problem has been corrected.
- If you use a cheat in a USB drive, you must not disconnect the drive (VAC cannot find the file = VAC Authentication Error)
* The "USB method" I will write to the end.
* Windows activators (like KMSpico) can be the cause of the problem.
* If nothing works, contact Steam Support (can be slow, but recommended)

[ - ] Requirements
- Have the CCleaner installed, and configured manually (the program does nothing automatic).
- Have the CCEnhancer installed (optional, I do not think you need it).
- Close CS: GO and Steam (should not be initiated until you have completed all of the steps).

[ - ] Instructions
1- Software conflict (check that you don't have any software that can give problems)
* In my case, it was obligatory to remove the ASC8

2- Run as administrator the cmd.exe (C:\Windows\System32). Then write every code that I will leave below:

Code:

"C:\\Program Files (x86)\\Steam\\bin\\SteamService.exe" /repair
bcdedit /deletevalue nointegritychecks
bcdedit /deletevalue loadoptions
bcdedit /debug off
bcdedit /deletevalue nx
del C:\Windows\Temp
del C:\Windows\Prefetch
del C:\Users\XXX\AppData\Local\Temp <-- XXX should be replaced by your username
ipconfig /flushdns
net stop dnscache
net start dnscache
fsutil usn deletejournal /n C: <-- Add all the units you use to play (C, D and G in my case)
fsutil usn deletejournal /n D: <-- Add all the units you use to play (C, D and G in my case)
fsutil usn deletejournal /n G: <-- Add all the units you use to play (C, D and G in my case)

* Then, verify that I have open ports, allowed the connection of Steam and CS: GO in the Windows Firewall. Like the Anti-Virus.

3- Run as administrator the CCleaner, Mark all the options (but ... you can uncheck some as...)

Code:

[ - ] Tab: Windows
- Advanced
Window Size/Location Cache
Wipe Free Space

[ - ] Tab: Applications
- Google Chrome
Unmark all

- Windows
AutoPlay Devices*
Compatibility Assistant*
QuickLaunch*
ShellBags*

Click to "Analyze", and then "Run Cleaner" (Do not save copies, clean all).
Now, in "Registry", mark all. Click to "Scan for Issues", and then "Fix selected issues..." (Mark all, you can save backup if you want to).

4- Restart the PC properly.

[ - ] USB method
* Credits to the user klurosu (well it is called in another forum).

1. Get a usb
2. Put dll v1 hotfix 1 and injector inside the USB
3. MAKE SURE YOU DO NOT START STEAM OR CSGO YET... THIS WILL GIVE YOU VAC ERROR
4. Inject the dll into a 32b program ( (screenpresso, lightscreen, camtasaia, blah,blah,blah)
5. Close all programs on the usb (like the injector) and unplug the USB
6. Start up STEAM and CSGO
7. Works like a charm. NEVER put the usb back in unless you completely close CS GO.
8. That's it

// Solved?

Thanks worked!
