Problem Connecting to License Manager
---------------------------
Provide your license server administrator with the following information:
Error Code = -42
Invalid parameter.
License path: @DESKTOP-XXXXX;【主機名脫敏】
FlexNet Licensing error:-42,147
ArcGIS for Desktop/Engine 10.2 cannot connect to previous versions of the ArcGIS License Manager.
Please contact your organization's License Administrator to ensure that your License Manager is version 10.2 or newer.
據大佬所說：arcEngine10授權部分代碼寫法的問題！bind綁定部分代碼重新寫，arcEngine9.3的授權部分代碼寫法在10.0版中有問題
可能是與AE許可綁定代碼有關。具體怎么回事，哪句所導致沒去驗證。
可能是用了下面語句，中某句或者是放在錯誤位置所導致。
//#region 初始化許可
//IAoInitialize m_AoInitialize = new AoInitializeClass();
//esriLicenseStatus licenseStatus = esriLicenseStatus.esriLicenseUnavailable;
////licenseStatus = m_AoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcInfo);
//licenseStatus = m_AoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeAdvanced);
//if (licenseStatus == esriLicenseStatus.esriLicenseNotInitialized)
//{
// MessageBox.Show("沒有esriLicenseProductCodeArcInfo許可！");
// Application.Exit();
//}
//else if (licenseStatus == esriLicenseStatus.esriLicenseUnavailable)
//{
// MessageBox.Show("沒有esriLicenseProductCodeArcInfo許可！");
// Application.Exit();
//}
//m_AoInitialize.CheckOutExtension(esriLicenseExtensionCode.esriLicenseExtensionCode3DAnalyst);
//#endregion
解決辦法
1.刪掉以上代碼。
2.重新添加控件
3.重新添加ESRI.ArcGIS.version、ESRI.ArcGIS.System引用
4.重新生成解決方案（如未改正錯誤重新生成解決方案會再次出現該問題。）
