We have hundreds of LMI free clients installed across LAN/WAN PCs.  With their change to limit of 10 free installations (and our successful deployment of VNC/TightVNC), we need to uninstall silently.  Any ideas?

Grab the uninstall string from the registry then use

Msiexec.exe /x string

Or you could use wmi in a script

  • In case if silent uninstall is not available using msiexec and there is a uninstall switch provided by vendor, u can try hiding the uninstall dialog using AutoIT script. i'll leave that as an assignment to you, to figure out how we can suppress the screen. I once implemented it with a friend of mine
  • FYI: The software GUID can be found in this location in the registry


    then your uninstall command would look something like this

    msiexec.exe /x {25892e17-80f6-415f-9c65-7395632f0223} /qn

Please tell us which version LogMain client do you use.


You can open the Regedit on a client and go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall. Search for LogMain in this location and you shold find the Uninstall registry entrys for this application. You can verify this if the DisplayName entry has the value LogMain or something related to the applications.

Read the value from UninstallString entry and use it to see if is a silent uninstallation or not. You can put the string here and we can help you to create a silent uninstallation string.

The solution: you were right - found the reg key, created Online Shell Script containing "msiexec.exe /x {string} /qn"

Side note: this did not work as script.sh in K1000.  Changed it to a .bat file and it worked like a champ for Windows 7 and XP.
