Uninstaller service should not depend on InstallLocation to be filled out

[ferventcoder]

The autoUninstaller looks for the existence of the registry key and the install path. However InstallPath could be empty as it is not required to be filled out. Only check InstallPath if it has a value.

Is this a fix for the issue discussed in this thread? I still can't get notepad++ to uninstall with autouninstaller enabled before installation. This is with Chocolatey 0.9.9.8.

@masaeedu I think we should followup with a new issue. It should work if you have enabled autouninstaller before uninstallation. The caveat is that if you had NPP already installed and then used choco to reinstall it, it may not have caught a registry snapshot.

@ferventcoder "The caveat is that if you had NPP already installed and then used choco to reinstall it, it may not have caught a registry snapshot."

I believe this is what happened to me as I am currently dealing with the same issue. What does one do in this case?

[aronovgj]

uninstall and reinstall. also autouninstaller should be on when you install

[alyssenko-ssi]

@aronovgj thanks- let me try that.

[ferventcoder]

Auto uninstaller doesn't need to be on when you install. It will always capture the snapshot during the install no matter what. It just may not have anything to capture if there is no change to the registry.

[aronovgj]

i was so sure...

My experience is that it doesn't capture the registry snapshot. Is there any Github issue opened to address this?

[ferventcoder]

@i-give-up So you don't have NPP already installed and it is installing and doesn't capture a snapshot? And you are on on the latest version of chocolatey (0.9.9.11 as of this question)?

[ferventcoder]

No ticket yet filed for that.

@ferventcoder I'm using choco 0.9.9.11. Testing the steps below with packages vlc and notepadplusplus.install

1. Install the software manually.
2. Install the software using choco install
3. Uninstall the software using choco uninstall

Both gave me the message

Skipping the auto uninstaller - No registry snapshot. 

Perhaps I should restart before installing with choco or is that supposed to matter?

[ferventcoder]

Step 1 is the issue, the snapshot can only detect registry changes. It may
see a change if there is a new version installed (no guarantees though).

You'd need to uninstall manually before the choco install and maybe a
reboot first before step 2.

You can always see the snapshots in
$env:ChocolateyInstall.chocolatey\pkgname.version.registry

Yeah, sorry if I wasn't being clear before.

What I meant to ask was that: seeing that the Auto Uninstaller doesn't work if you install a package via choco over an existing manual installation, is there any plan to make Auto Uninstaller work in such cases?

[ferventcoder]

Yes, but it's based on package opt-in that tells the install where the key is. This also has the nice side effect of not running the installer if it is already installed.
