Coils – Logo customization unlock

Customer guide · 23/10/2026

What it is for

With an unlock code you can change again the logo and the company data printed by Coils.

The Tools > Customize logo item can be used once. After the first save it disappears from the menu and Tools > Unlock logo customization appears in its place. With an unlock code from Unilab, Customize logo becomes available again for one new customization.

Procedure

  1. Open Coils on the PC where you want to change the logo, with your usual Windows user.
  2. Choose Tools > Unlock logo customization. A window shows the Request code, in the form XXX-XXX-XXX.
  3. Press Copyand send the request code to Unilab (for example by email), with the name of your company.
    • While you wait for the answer you can close the window and Coils too: the request code stays the same until it is used.
  4. Unilab answers with an 8-digit Unlock code, in the form 1234-5678.
  5. Open Tools > Unlock logo customization again, type the unlock code and press Apply. A message confirms the unlock.
  6. Choose Tools > Customize logo, select the new BMP logo file, type the header with the company data (5 lines at most) and press Apply.
  7. After the save, Customize logo disappears again. Another change needs a new unlock code.

Good to know and troubleshooting

  • One code, one PC, one customization. An unlock code works only for the request code it was made from. So it works only on that PC and for one logo save.
  • Same Windows user. Enter the unlock code with the same Windows user who copied the request code.
  • The logo: a BMP file of 750 KB at most. The header: 5 lines at most; lines longer than 60 characters are flagged.
ProblemWhat to do
"Invalid unlock code"Check that you typed all 8 digits. If you asked for more than one code, use the one for the last request you sent.
The request code has changedThis happens on another PC or after a customization already done. Send the new request code to Unilab.
I cannot find Unlock logo customizationIt appears only when Customize logo is not available. If you see Customize logo, you can already change the logo.
I cancelled the customizationThe unlock is still valid: Customize logo stays in the menu until you save.
