Hi,

I am using Google Adwords Api for LXRPlugin[Excel AddIn] in visual studio 2017 c# project. 

The visual studio solution contains GoogleAPIIntraction as the main project.

 The solution runs successfully before .exe file is packaged.

After creating .exe file and installing the setup file I am getting the error.

I am not able to debug the .exe project step by step, but In log file following messages are shown in the build.

DownloadDllFiles() An exception occurred during a WebClient request.
DownloadXMLFiles() An exception occurred during a WebClient request.
Clicked on Add account button
selectd package type:agency
 Adword autherization login form

I am sharing the code for DownloadDllFiles and DownloadXMLFiles.

 private void DownloadDllFiles()

        {

            List<string> dllFiles = new List<string> { "Google.Ads.Common.dll", "Google.AdWords.dll" }; //"Google.Apis.Analytics.v3.dll", "Google.Apis.Auth.dll", "Google.Apis.Auth.PlatformServices.dll", "Google.Apis.Core.dll", "Google.Apis.dll", "Google.Apis.PlatformServices.dll" };

            string strAppDir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);

            strAppDir = strAppDir.Remove(0, 6);

            System.Net.WebClient wc = new System.Net.WebClient();

            foreach (var dll in dllFiles)

            {

                string filePath = strAppDir + dll;

                try

                {

                    wc.DownloadFile(Globals.ThisAddIn.LXRXMLFilePath + dll, filePath);

                }

                catch (Exception ex) { LogWriter.Instance.CreateEntry("DownloadDllFiles() " + ex.Message); }

            }

        }

        private void DownloadXMLFiles()

        {

            List<string> xmlFiles = new List<string> { "ACCOUNT_PERFORMANCE_REPORT.xml", "ADGROUP_PERFORMANCE_REPORT.xml",

                "AD_EXTENSIONS_PERFORMANCE_REPORT.xml", "AD_PERFORMANCE_REPORT.xml", "AGE_RANGE_PERFORMANCE_REPORT.xml",

                "AUDIENCE_PERFORMANCE_REPORT.xml", "AUTOMATIC_PLACEMENTS_PERFORMANCE_REPORT.xml", "CALL_METRICS_CALL_DETAILS_REPORT.xml",

                "KEYWORDS_PERFORMANCE_REPORT.xml", "SEARCH_QUERY_PERFORMANCE_REPORT.xml","PAID_ORGANIC_QUERY_REPORT.xml" };

            string strAppDir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);

            strAppDir = strAppDir.Remove(0, 6);

            strAppDir = Path.Combine(strAppDir + "\\Xmls\\");

            System.Net.WebClient wc = new System.Net.WebClient();

            foreach (var xml in xmlFiles)

            {

                string filePath = strAppDir + xml;

                try

                {

                    wc.DownloadFile(Globals.ThisAddIn.LXRXMLFilePath + xml, filePath);

                }

                catch (Exception ex) { LogWriter.Instance.CreateEntry("DownloadXMLFiles() " + ex.Message); }

            }

        }

The following message is shown in log file when i select Google Analytics.
