GWT Developer plugin for Chrome and Internet Explorer - error preventing installation

Question

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.

Enable the GWT Developer Plugin in Chrome.

Check for other plugin that is installed on Chrome.

Click on plugins for other systems to get more GWT Developer plugins.

Here is the URL for GWT missing-plugin.

Click on required GWT plugin and simply click on save button as shown below for IE9.

This might be useful for you:

1. Create shortcut Chrome to desktop.
2. Right click to shortcut and choose properties.
3. Click to Compatibility tab
4. Inside Compatibility mode check "Run this compatibility mode for:" and choose Window 7.
5. Apply and Ok.

Answer 4

If you want to think Agile, here's what I adopted as a solution:

superDevMode is not practical, it takes forever to compile each time on my i7 with 8Gb of memory.

The solution I adopted is that I'm using FF for developement and I validate everything is fine only after GWT compiling on chrome (once in a while for the pauses).

Seriously I didn't see the point of having dev mode working on all browsers. In addition it runs curiously faster on FF than on Chrome (under windows). For Ubuntu (actually) I had to downgrade my FF to the version 24 to have it work (but since it's only a dev machine it doesn't bother me)

p.s: superDevMode might compile faster if optimized, hoestly I didn't try it: increasing the localWorkers could reduce compile time and make superDevMode a good solution, but I can't tell you; I didn't try that: http://mojo.codehaus.org/gwt-maven-plugin/compile-mojo.html#localWorkers
