Hello,

I am using Umbraco version 7.5.3., but would like to downgrade the version of Forms that comes with it. The current version installed in UmbracoForms 4.2.1

I would like to use version 4.1.5

I have tried uninstalling, but keeping getting the error (see below) and and when i close the uninstalling window is froze.

Anyone has an idea please? Much appreciated.

Regards, Ahsinah
