I think you misunderstood. I acknowledged your suggestion by replying with "Thank you for the suggestion". I then said we need to speak with DNN Corp. first and see if there's something we can do with the manifest itself. If we can uninstall cleanly by the manifest, the extra message won't be needed at all.

In either case, for any module, we always encourage the users to do their due diligence and read through the Users manual before doing any kind of installation. The Users manual talks about installation requirements, how it works and how to uninstall. These are all equally important topics that a user should be aware.

Well, it might be that my native language <> English, so explaining, writing and understanding English create a barrier.

All details about the install manifest can be found in the DNN Wiki:

There is no such thing as an UnInstall interface, like the iUpgradeable interface you have implemented to be used during installation.

As for RTFM: please understand that there might be a gap in time as well as person between the moment of installation and the moment of uninstall. A simple text explaining what to do would help (and prevent).

As for language: a suggestion (request): please implement the standard DNN localization. It would make the module more in line with common DNN module development standards and usable for others not speaking English (and there are a lot of countries that don't).
If you feel unfamiliar or uncomfortable with lcoalization, please ask. We might be of assistance.

No problem, I just want to make sure you don't feel we push aside your feedback. We already started inquiring about what better ways to uninstall. As you noted, there is no IUninstall interface, only IUpgradeable. We have pushed to put in a feature enhancement to DNN for it.

We will add to our future todo to localize the Optimizer and we understand the importance of it. Our Revindex Storefront software, for example, is already partially localized for 5 languages and we recently assisted in a DNN Corp. sponsored localization tool that is now available to community for download on Codeplex.

Thanks,
