Error 4200 “Login failed” means your computer’s date is set earlier
than your licence start date; fix the Windows clock and restart Vatrix.
Error 4201 “System access failed” means the Product ID in the database
does not match this computer; send the new Product ID to Vatrix support
on WhatsApp +971 50 428 2953 and enter the activation code you receive.
Neither error deletes your data, and neither means your licence has
expired. Remote support is included with every Vatrix licence for 1
year.
This applies to all editions: Restaurant, Retail, Retail 2nd Edition,
Salon and ERP (source: v96.39).

Fix error 4200 “Login failed”
This is the most common one after a power cut or a dead CMOS battery,
when the PC wakes up thinking it is 2015.
- Close the Vatrix login window.
- Look at the clock in the bottom-right corner of Windows. If the date
is wrong, that is the cause. - Right-click the clock → Adjust date/time.
- Turn on “Set time automatically” and “Set time zone automatically”,
or set the correct date and time manually (UAE is UTC+4). - Confirm the date is now today’s date.
- Open Vatrix again and log in.
If the date goes wrong again after every restart, the CMOS battery on
the POS motherboard is flat. Any PC technician can replace it; Vatrix
Hardware Care and Complete Care customers can WhatsApp us (see the
Vatrix Care brochure for what each plan covers).
Error 4200 is not a licence problem. You do not need a new activation
code.
Fix error 4201 “System
access failed”
Vatrix ties each licence to a Product ID generated from the computer.
When the database is restored on a different PC, a major hardware part
is changed, or Windows is reinstalled, the stored Product ID no longer
matches and Vatrix stops at error 4201.
- Click OK on the error. Vatrix opens the activation window
automatically. - Note the Product ID shown on that window (copy it or take a clear
photo). - Send the Product ID on WhatsApp to +971 50 428 2953 with your shop
name and TRN or invoice number so we can find your licence. - Support checks the licence and replies with an activation code.
- Enter the activation code in the activation window and click
Activate. - Vatrix opens with all your items, customers and invoices
intact.
Your existing data is not lost. The database is already on the PC;
only the licence check needed updating.
Why 4201 usually appears
- You moved Vatrix to a new computer and restored a backup. This is
expected; see move Vatrix
POS to a new computer. - A technician replaced the motherboard, SSD or another major
part. - Windows was formatted and reinstalled.
- The database was copied to a second counter without setting up SQL
Server sharing.
Before you call: two checks
| Check | How |
|---|---|
| Is the Windows date correct? | Look at the taskbar clock; fixes 4200 |
| Did anything change on the PC recently? | New PC, new Windows, repaired hardware; explains 4201 |
In practice
A cafeteria in Ajman had a power cut overnight. The next morning the
POS showed error 4200. The cashier fixed the Windows date, restarted
Vatrix and was billing within two minutes. A month later the owner
bought a new POSBOLT PC, restored the Google Drive backup, saw error
4201, sent the Product ID on WhatsApp and received the activation code
the same morning.
Keep the automatic scheduled backup on with Google Drive sync so a
hardware failure never costs you data: see backup and Google Drive
sync.

FAQ
Will I lose my invoices if I get error 4201? No. The
database is unchanged. Only the licence check needs a new activation
code.
Is there a charge for the activation code? Remote
support is included for 1 year with every licence. After that, an annual
licence renewal (ARL, AED 660 per year including VAT) keeps support
active. Without a renewal, support is charged per incident and
re-activation on a new PC is a paid service.
Can I fix error 4201 myself without WhatsApp?
No. The activation code is generated by Vatrix support from your Product
ID.
I set the date but error 4200 still appears. Restart
Vatrix fully after changing the date. If the date resets on reboot, the
CMOS battery needs replacing.
What is error 4202? A licence validity mismatch.
