Unable to install the uninstalled Plugin

[shubhi_shubhi]

Hi Team,

I am having a problem reinstalling a plugin that I uninstalled earlier because of a version change.

Now when I try to install it again, it says the plugin is already installed.

While uninstalling, I forgot to select the option to remove all data and tables. But after that, I manually deleted all the tables and data.

Still, the system shows that version 4.2.1 is already installed.

Please help me fix this issue.

Thank you.

ahoy @Ankur Bawiskar,

it has changed some time ago and plugins can be uninstalled:

Respecting the dependencies but without it, it can be done. Please take this as an opportunity to learn the current status.

Also, there might be some quirks such as - installing strategic portfolio planning, then uninstall it and installing portfolio planning, the corresponding workspace will keep the Strategic Portfolio Planning name despite it is not SPW but PPW :)) but it might be some unintentional bug by ServiceNow..

ahoy @shubhi_shubhi,

I can see that the plugin in discussion is unavailable for PDIs, which can mean that it was installed from the Store or is a subject to some licence/purchase.

My PDI:

So I would recommend you to create a case from the support portal

I didn't notice this, thanks for informing.

If this is a new feature I didn't find any docs for this either which ServiceNow should have

I just found this which says it can't be uninstalled

After deleting all the related TABLES of the plugin and ROLES 

It worked and I was able to install the plugin again

Deleted Below Table but make sure Application Attribute should be the correct:

1) sys_security_acl_role

2. sys_app_application

3) sys_app_module

4) sys_user_role
