Extension already installed! - How to upgrade extension to new version if we can't upload

[padaliyajay]

What version of OpenCart are you reporting this for?
Opencart 4

Describe the bug
If extension was already installed before and if new version available then i can't upload same named file again. if you upload then get error "Extension already installed".

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Extension -> installer'
2. Click on 'Upload button'
3. See error

Expected behavior
It should be accept file and overwrite existing extension files so we can update extension to new version

uninstall and delete

[danielkerr]

then reinstall. i will try to come up with a quick fix before next release.

[padaliyajay]

ok but this is not right way because if we uninstall extension then it will also remove it database.

So it should be.
1). upload file
2). if already installed then delete existing extension files and add new files
3). change extension version in oc_extension_install table and reset file path in oc_extension_path

Do a version check.

In install.json opencart.ocmod.zip the error is an extra comma.
