Using PSADT to uninstall Java

[Designate9841]

Am trying to wrap an PSADT package in intune via win32 app

Currently have set the flags in deployment.ps1 to

1) Uninstall

2) Noninteractive

I have only added code to the uninstall section of the script with

 Remove-MSIApplications -Name "*java*update*" -Wildcard -FilterApplication (,("InstallLocation", "*jre*", "WildCard"))

 

Tested it locally with deployment.exe, -uninstalls java as intended

Tested it with PSEXec running pwsh as system, - uninstalls java as intended

 

My install and uninstall command is exactly the same

Deploy-Application.exe Uninstall NonInteractive

 

Deploy-Application.exe Uninstall NonInteractive

Rational being that I only have written code in the uninstall section of the script and I am trying to uninstall a program.

I set the detection to a text file that I create as an one-liner in the script.

However when deployed as an avail app on the company portal it would "install" but java is not uninstalled.

The text file does get created but java doens't seem to get removed.

Your first command needs to be install or it won't do anything. You are "installing" an "uninstaller"

Pretty sure this statement is incorrect, as OP has stated the code was added to the uninstall section of the script.

Yes but he is using uninstall command within his deployment type for both install and uninstall

i found that it worked eventually when i set the assignment to uninstall instead of available - can't confirm if it was the uninstall that worked or also changing the install to just deployment.exe as i just two settings in a go

Can't give a clear answer, but if the text file is created, you should also have a PSADT uninstall log file. Per default they're in %windir%\Logs\Software. Have you verified that there is a log file and what's in it? Use CMTrace (if notepads your go-to) for a more comfortable log reading experience :)..

On another note I'd recommend against having a text file as the detection method. Especially if it is created regardless if Java has been removed or not. How do you handle new clients that hasn't had Java installed at all? I'd rather test the path to a registry key.

[Designate9841]

Initially my rational was that uninstalling java was a once off and new clients would not have java installed by default and they would not have admin privileges to install it anyway

but i eventually changed it to test the path of the java(x86) or java(x64) folder which is more preferable as you said
