Scripting Question

Silently Uninstalling Epson Drivers through Sccm Deployment

01/15/2015 5583 views
Just wondering if someone can help with an issue I have encountered trying to uninstall Epson software silently via a script. I have an upgrade approaching and need to completely uninstall these drivers automatically. First I tried the following vbscript:

On Error Resume Next

Dim strComputer
strComputer = "."

Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colSoftware = objWMIService.ExecQuery("Select * from Win32_Product Where Name LIKE 'EPSON%'") 

For Each objSoftware In colSoftware 
wscript.echo "Uninstalling: " & objSoftware.Name 

This did work for only one of the four installed epson softwares (The one that via: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall was an msi), the other uninstall strings were listed as setup files in the InstallShield Installation Information directory.  I tried these strings directly through a command prompt using different switch combinations (-runfromtemp -l0x0009 -removeonly /s /sms /silent /verysilent).  I cannot seem to get them to uninstall. 
Any suggestions on any other methods I could try to get these applications uninstalled completely?

  • Have you considered running a full capture on the installation of these drivers so that you can grab the various uninstallstrings that are generated in the registry? I presume that an uninstall from Add/Remove programs does remove the drivers completely? Are you running the uninstall as local system or as an elevated user? From what I recall, there is some printer information in HKCU which of course cannot be accessed by a local system account.
  • An uninstall from Add/Remove programs does work at completely uninstalling drivers and software. The issue is to script this. Although I get the uninstaller to begin, I can't find the right switch to override the yes/no prompt confirming uninstallation and have the software fully uninstall without intervention. I've tried -versysilent, -silent, -suppressmsgboxes, -sp and various combinations as well as being sure to use the run from temp switch so it can fully delete itself after
  • As you have mentioned that these are InstallShield installers, have you tried to create a response file (-r -f1... or /r /f1... switches) and then execute it silently (-s or /s)?

You can check in registry at:
Search the GUID's for your software, then the UninstallString row can be used for uninstalling.
Or you can put together a nice script that goes over this, search in the DisplayName then read and execute the UninstallString.

Using the Win32_Products very buggy and can also trigger reinstallation of other software.
There are multiple articles on this matter.

  • I have tried running the exact uninstall string from that location but it still requires user intervention to confirm the uninstallation. The issue is that I want to uninstall them silently without needed user intervention and therefore be able to script this and run via a package and deploy to multiple systems to automate the task.
    • I see, some office appliation have the same problem.
      The solution I use there is AutoIT, with this you can create scripts that can take over these "user actions".
