Example

string returnMsg = license.ValidateLicenseExe(licenseKey, computerID, false, false);
bool ret = false;
bool needsActivation = true;

int nStatus = (int)license.GetStatus();

if (IsTrue(nStatus, (int)ELicenseStatus.EKeyInvalid) ||
    IsTrue(nStatus, (int)ELicenseStatus.EKeyProductInvalid) ||
    IsTrue(nStatus, (int)ELicenseStatus.EKeyMachineInvalid) ||
    IsTrue(nStatus, (int)ELicenseStatus.EKeyExceededAllowedInstances) ||
    IsTrue(nStatus, (int)ELicenseStatus.EKeyTampered))
{
    // the key is invalid
    ret = false;
}
else if (IsTrue(nStatus, (int)ELicenseStatus.EKeyVersionInvalid))
{
    // wrongProductVersion
    ret = false;
}
else if (IsTrue(nStatus, (int)ELicenseStatus.EKeyDemo))
{
    // The key has an expiry date

    if (IsTrue(nStatus, (int)ELicenseStatus.EKeyExpired))
    {
        // the key has expired
        ret = false;        
    }
    else
    {
        // the key is still valid
        ret = true;
        // call license.DaysLeft to get the remaining days
    }
}
else if (IsTrue(nStatus, (int)ELicenseStatus.EKeyPermanent))
{
    // the key is valid and permanent
    ret = true;
}

if (ret == true)
{

    if (license.IsActivationLicense (license.LicenseType))
    {
        needsActivation = true;
        ret = false;
