Java – GWT Developer plugin for Chrome and Internet Explorer – error preventing installation

google-chromegwtinternet explorerjava

I am trying to install the GWT Developer plugin for Chrome (Version 34.0.1847.131 m) and I get the following error "This application is not supported on this computer. Installation has been disabled. The following problems are detected:" and "NPAPI plugin is required by this app". Is there a way around this?

I have installed Microsoft Visual C++ 2008 SP1 Redistributable Package as suggested by one answer.

I am also trying to run in Explorer (version 11) and it requires me to download the GWT Developer plugin for Firefox. Which then requires content to be opened in a new window. I then elect to open "gwt-dev-plugin.xpi". When it finishes downloading it requests me to save it (if I open it it just download again). Is there a way around this?

I am running on Windows 8.1.

I am also trying to run in Explorer (version 11) and it requires me to download the GWT Developer plugin for Firefox.

To avoid that, open IE11 dev tools and under the "Emulation" menu change the "Document mode" from "Edge" to "10". The page should refresh and from there you should be able to install the GWT plugin for IE.

Once it's installed you can fall back to the "Edge" document mode.

Worked for me.

But as @apanizo said, I'd use the Super Dev Mode if possible. The dev mode is already not supported anymore in the latest firefox and it is going to be the same for the upcoming Chrome 35. No clue about IE though.
