Uninstall Issue

[CyberCitizen]

Hi Guy's,

I am in the process of creating an upgrade package for one of our installs (Buildsoft).

I have got the install etc working ok, the issue is there is a previous install which we need to remove before we can upgrade.

It is installed via a MSI to the C:\Esw. When I attempt the Lansweeper Uninstall, it fails.

So I have tried calling the uninstall via the below command.
wmic product where name="Buildsoft Global Estimating - Network" call uninstall /nointeractive

Now this uninstalls successfully within an administrative DOS window. Returns the below results.
Executing (\\SGH00700\ROOT\CIMV2:Win32_Product.IdentifyingNumber="{0C70EE82-949D-4454-97C6-57DF207C257A}",Name="Buildsoft Global Estimating - Network",Version="1.0.0")->Uninstall()

Method execution successful.

Out Parameters:
instance of __PARAMETERS
{
ReturnValue = 0;
};


Now running the same command via Lansweeper fails, and returns the below result.
Executing (\\SGH00700\ROOT\CIMV2:Win32_Product.IdentifyingNumber="{0C70EE82-949D-4454-97C6-57DF207C257A}",Name="Buildsoft Global Estimating - Network",Version="1.0.0")->Uninstall()

Method execution successful.

Out Parameters:
instance of __PARAMETERS
{
ReturnValue = 1603;
};


Any assistance would be greatly appreciated as I would like to get this upgrade done sooner, rather than later.

No problem. It's always useful to figure this stuff out as it might help others in the future.

Since it is installed via an MSI, can't you use the MSI uninstaller to remove it? Similar to the "MSI-Uninstaller - Firefox" example that is built-in.

Hi Charles,

Found the issue, the installer / uninstaller references files that are stored on a separate drive (V Drive). We have to map this drive when installing as it writes some files to this path, as such the uninstall required that as well. I have now successfully uninstalled the application by mapping the drive first.

Sorry about this, stupid application.

Hi Charles,

Unfortunately no, it returns the following error.
Result: Deployment ended: Fatal error during installation. Stop(Failure)

The only way I have been able to remove this product is using the WMIC command listed but in a DOS window run manually, fails via a deployment. Or manually via appwiz.cpl (Add / Remove Programs).
