You can simply start the Wireshark installer without any command line parameters, it will show you the usual interactive installer.

For special cases, there are some command line parameters available:

"wireshark-win32-1.9.0.exe /NCRC /S /desktopicon=yes
  /quicklaunchicon=no /D=C:\Program Files\Foo"

I've created 2 scripts, one for installation and one for removal.

==========Install===========

The script is created for Wireshark-win64-1.8.4.exe, but you can modify it for any version.

Install.vbs:

 Option explicit

'=============================
'==== Install Wireshark ====
'=============================
Dim strScriptPath : strScriptPath = Left(WScript.ScriptFullName, InStrRev(WScript.ScriptFullName, "\")-1)
Dim objWSH
Dim strArch
Dim SetupCMD
Set objWSH = CreateObject("WScript.Shell")

DisableSecurity()
'Installation will be done without Desktop Icon and Quicklaunch Icon
SetupCMD = """" & strScriptPath & "\Wireshark-win64-1.8.4.exe" & """" & " /S /NCRC /desktopicon=no /quicklaunchicon=no"
objWSH.Run SetupCMD


'=================================
'==== Install WinPCap 4.1.2 ====
'=================================
Dim MSIInstalCMD
Dim ProductCode

ProductCode = "{342A9145-3489-4533-A21D-C4D9AEEE2F9D}"
MSIInstalCMD = "msiexec /i """ & strScriptPath & "\WinPCap 4.1.2 x64 en.msi"" /qn"

objWSH.Run MSIInstalCMD,,True

'=============================
'==== Sub's and Functions ====
'=============================

Sub DisableSecurity()
	Dim objEnvProc, objWSH
	Set objWSH = CreateObject("WScript.Shell")
	Set objEnvProc = objWSH.Environment("PROCESS")
	objEnvProc("SEE_MASK_NOZONECHECKS") = 1
End Sub

• Because in silent mode installation the WinPCap is not installed during Wireshark installation I added a section to install WinPCap msi using msiexec command. You can find the section to line 18.

• The installation is completely silent.
• Important: The Wireshark executable name and WinPCap msi name are hardcoded in the installation script. You can modify them if you want. You can find them to line 13 and line 24.
  

 =========Remove==========

For removal I created a script to read the UninstallStrig registry key from:

• "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\Wireshark\UninstallString" - if the application is installed on a x86 Windows
• "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Wireshark\UninstallString" - if the application is installed on a x64 Windows

Remove.vbs:

Dim UninstallStr_x64

UninstallStr_x86 = "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\Wireshark\UninstallString"
UninstallStr_x64 = "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Wireshark\UninstallString"

DisableSecurity()

If ProcArchitecture("x86") then
	If ExistRegKey(UninstallStr_x86) then
		UninstallStr = GetRegValue(UninstallStr_x86)
		Launch_App UninstallStr, "/S"
	End IF
End if

If ProcArchitecture("AMD64") then
	If ExistRegKey(UninstallStr_x86) then
		UninstallStr = GetRegValue(UninstallStr_x86)
		'msgbox UninstallStr
		Launch_App UninstallStr, "/S"
	End IF
	If ExistRegKey(UninstallStr_x64) Then
		UninstallStr = GetRegValue(UninstallStr_x64)

End Function

• The removal is totaly silent

Important: Both scripts have to be placed in the same folder with Wireshark setup executable and WinPCap 4.1.2 x64 en.msi.
