The software stops working on the day an annual license expires. When that happens Analyse-it shows one more notice, which says that you have turned the notices off and that the person must contact you. The notice does not offer to open analyse-it.com. It is shown once for each expiry date, so renewing the license shows it again the next time that license expires.
Set this registry value on each computer:
HKEY_LOCAL_MACHINE\Software\Analyse-it\Analyse-it for Microsoft Excel
Value name DisableLicenseNotices, type REG_DWORD, data 1. Set it to 0, or delete it, to show the notices again.
Use Group Policy Preferences to set it on many computers.
Analyse-it no longer shows license expiry or maintenance renewal notices, apart from the final notice for an annual license that has expired. Check the expiry dates yourself and renew before they pass; see Checking maintenance expiry and renewing.
This setting changes only the notices shown by the software on that computer. E-mail about maintenance expiring is still sent to the people registered on the license.
