Problem running deployed application online only - C# .NET 3.51

[Jon Braunsma]

I have another strange issue. I deployed my project with "available online ony" and it works fine for everyone except for one particular user. This user is on a college campus and is apparently using http proxy. Is there a specific port used when executing or something I need to be aware of to help troubleshoot this issue more? It is only for one user. It works fine for everyone else. Here is the log: The following properties have been set: Property: [AdminUser] = true {boolean} Property: [ProcessorArchitecture] = Intel {string} Property: [VersionNT] = 5.1.3 {version} Running checks for package 'Windows Installer 3.1', phase BuildList The following properties have been set for package 'Windows Installer 3.1': Running checks for command 'WindowsInstaller3_1\WindowsInstaller-KB893803-v2-x86.exe' Result of running operator 'VersionGreaterThanOrEqualTo' on property 'VersionMsi' and value '3.1': true Result of checks for command 'WindowsInstaller3_1\WindowsInstaller-KB893803-v2-x86.exe' is 'Bypass' 'Windows Installer 3.1' RunCheck result: No Install Needed Running checks for package '.NET Framework 3.5 SP1', phase BuildList Reading value 'SP' of registry key 'HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5' Read integer value 1 Setting value '1 {int}' for property 'DotNet35SP' The following properties have been set for package '.NET Framework 3.5 SP1': Property: [DotNet35SP] = 1 {int} Running checks for command 'DotNetFX35SP1\dotNetFx35setup.exe' Result of running operator 'ValueGreaterThanEqualTo' on property 'DotNet35SP' and value '1': true Result of checks for command 'DotNetFX35SP1\dotNetFx35setup.exe' is 'Bypass' '.NET Framework 3.5 SP1' RunCheck result: No Install Needed Launching Application.
