Cannot uninstall Sophos AV Standalone from home machine - because Sophos client firewall cannot be removed either.

Hello Graham,

according to the message the LaunchCondition checking the OS version fails - though it shouldn't.

Could you try running it from the command line MsiExec.exe /X{A805FB2A-A844-4cba-8088-CA64087D59E1} /qn REBOOT=SUPPRESS /L*v %windir%\Temp\SCFUninstallLog.txt and post the log?

Christian

Thanks Christian

I tried that, ran it from Windows Run... that didn't work

Then I opened dos command line
cmd then C:\ and tried again.

Went to uninstall and the error message repeated.

Graham

Hello Graham,

after running it from the (elevated) command line there should be the log in C:\Windows\Temp\ and maybe it gives some insight.

Hello Christain

Nothing in Windows\temp

Searching my system i cannot find msiexe.exe.

I am running Windows 10 and a google search would indicate that msiexe.exe is not a Window 10 system file

Graham

Hello Graham,

it's msiexeC.exe.

Christian

Hello Christian

The file is on the system.

i have run again from both Windows & Cdm. No file has been created in C:\Temp, Uninstall still shows the same error code.

Sorry for being a pain.

Graham

Hello Graham,

run again from both
msiexec.exe should be run from an administrative cmd window (Command Prompt (Admin)). The command I've suggested should write to C:\Windows\Temp\SCFUninstallLog.txt (but if it's not running from an Admin prompt it's likely not able to do so).

Uninstall still shows the same error code
msiexec.exe /x is an uninstall, with this product code it is the same uninstall that runs from Programs and Features. I've asked you to run msiexec so that a log is created which is needed to determine why the uninstall fails. I did not expect msiexec to succeed, and naturally if it fails Uninstall will also still fail - but in case msiexec succeeds SCF would be gone from Programs and Features.

Christian

Works & I have the log file.

Hope this helps... sorry i really should read instructions more closely... Thanks

Graham

Hello Graham,

1605 means the product isn't installed. Is SCF still in Programs and Features (you might also want to check the registry as outlines under Gather the uninstall commands in this How to ... article)?

Christian

Good morning

There were two entries one for Sophos Client Fire Wall, the other for Sophos Anti-Virus

MsiExec.exe /X{12C00299-B8B4-40D3-9663-66ABEA3198AB}   ..sophos client firewall
MsiExec.exe /X{65323B2D-83D4-470D-A209-D769DB30BBDB} .. sophos Ant-Virus

I followed the instruction and attach the log file.

However, when i tried again to un-install the Sophos Firewall still gives the same error code.

Have a great weekend and i love the photo.

Graham

I wonder if you could bypass this by editing the MSI file you're using to uninstall.  How about:

1. Locate the file "Sophos Client Firewall.msi" which is in the AutoUpdate Cache directory. E..g \programdata\sophos\autoupdate\cache\...  I assume this is the same version as the version installed.  If not maybe try taking a copy of C:\Windows\Installer\ca4ec1.msi and editing that.

2. Make a copy of it "Sophos Client Firewall.msi" so you have a backup.

3. Create a new text file called editMSI.vbs (ensure it has the extension .vbs and not .vbs.txt) and paste the following.

Dim oInstaller : Set oInstaller = CreateObject("WindowsInstaller.Installer")
Dim oDatabase : Set oDatabase = oInstaller.OpenDatabase(WScript.Arguments(0),1)
Dim sql : sql = "delete FROM `InstallExecuteSequence` WHERE `Action` = 'LaunchConditions'"
Dim oUpdate : Set regView = oDatabase.OpenView(sql)
oUpdate.Execute
oDatabase.Commit
oUpdate.Close
Set oUpdate = Nothing
Set oDatabase = Nothing
Set oInstaller = Nothing

4. Save the VBS file next to the "Sophos Client Firewall.msi" file.

5. In a command prompt CD to the location of the file and run:
cscript editmsi.vbs "Sophos Client Firewall.msi"

This should update the file  "Sophos Client Firewall.msi", deleting the LaunchConditions action from the InstallExeccuteSequence table.

6. Once edited, you could use this MSI to uninstall.

MsiExec.exe /x "Sophos Client Firewall.msi" /qn REBOOT=SUPPRESS /L*v %windir%\Temp\SCFUninstallLog.txt 

If this fails, maybe change the VBS line:

Dim sql : sql = "delete FROM `InstallExecuteSequence` WHERE `Action` = 'LaunchConditions'"

To

Dim sql : sql = "delete FROM `InstallUISequence` WHERE `Action` = 'LaunchConditions'"

To update the MSI file a second time (updating the other table that references this action) before retrying.

Hope it help.

This message:

Failed to grab execution mutex. System error 258.

would suggest that MSI is performing another installation.

If you wait/reboot and try again, do you keep getting this?
