Install 7zip

Create SNMP Tester portable

Extract Paessler SNMP Tester.zip to c:\install\

Extract UniExtract2 to c:\install

Run UniExtractUpdater_NoAdmin.exe and allow it to update

Run UniExtract.exe

Select Next, Next, Finished in the wizard to skip initial setup.

Select Archive/Installer to extract

Select the “c:\install\Paessler SNMP Tester Setup.exe” file

Select the destination directory as “C:\install\Paessler SNMP Tester Setup”

The SNMP Tester files will be extracted to that directory.

If you receive a message that UniExtract is not compatible with the version of installer, try updating UniExtract.

Create the archive

Select all the files in the SNMP Tester Extracted directory, and create a 7z archive in the c:\install directory.  Name the file snmptest.7z.  Ensure that the snmptest.exe file is the root of the 7z archive, not a subdirectory.

Create the executable

Extract the 7zSD.sfx file from the LZMA SDK \ bin directory to c:\install

Copy the mt.exe file to c:\install

Prepare a manifest to prevent needing to runas admin

Create c:\install\SNMPTester.manifest containing:

<?xml version="1.0" encoding="utf-8"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
   <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
      <application>
         <!--application support for Windows Vista -->
         <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"/>
         <!--application support for Windows 7 -->
         <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>
      </application>
   </compatibility>
   <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
      <security>
         <requestedPrivileges>
            <requestedExecutionLevel level="asInvoker" uiAccess="false"/>
         </requestedPrivileges>
      </security>
   </trustInfo>
</assembly>

Prepare the command to run after extract

Create c:\install\config.txt file containing:

 ;!@Install@!UTF-8!
Title="SNMP Tester"
RunProgram="snmptest.exe"
;!@InstallEnd@!

You should have a number of files in c:\install

Apply the manifest

Open a command prompt, navigate to c:\install and run the following command

mt.exe -manifest "SNMPTester.manifest" -outputresource:"7zSD.sfx;#1"

Create the executable

copy /b 7zSD.sfx + config.txt + SNMPTest.7z SNMPTester.exe

That will output a self extracting archive (c:\install\SNMPTester.exe) that runs snmptest.exe and remove the temp files upon completion.

You can move c:\install\SNMPTester.exe to where it is needed and remove all files in c:\install
