Number keypad / numlock not working in IE Tab

If you are unable to use the numbers in the keypad when using IE Tab, the problem is likely caused by an anti-virus program / feature called WebRoot SecureAnywhere Identity Shield.  They say they are working on a fix for this problem, but here is a workaround:

You can fix this problem by running this program:

If the tool is run without arguments, it will modify the registry and prompt if ID Shield now has control of Num-Lock (Enabled) or if ID Shield no longer has control (Disabled). It will then ask for a reboot to complete the process.

If the tool is run with an argument it will be run silently (for example: though Agent Command – Advanced – Download and run a file). Pass it one of the following arguments:

-disable turns OFF ID Shield’s control of Num-Lock (meaning it is now Disabled). The following are also valid arguments (/off, -off, /disable).

-enable turns ON ID Shield’s control of Num-Lock (meaning it is now Enabled). The following are also valid arguments (/on, -on, -enable).

If the tool is run with two or more arguments nothing will happen.

Note: The registry key that this affects is HKLM\SYSTEM\CurrentControlSet\Services\ikbevent “DWORD”:Type 0x01 with this key in place ID Shield’s control of Num-Lock is disabled and with it removed it is enabled.

Deploying Extensions Locally

Web Store Deployment

We have online documentation that describes the preferred deployment mechanism for the IE Tab extension:   ie-tab-documentation#deployment

This mechanism installs the IE Tab extension from the Chrome Web Store and the installed version will be automatically updated when the IE Tab extension is updated.

Problems with Web Store Deployment

However, there are a couple of reasons why this mechanism may not work for some customers:

  1. Corporate firewall.  Some enterprise users are behind a corporate firewall that restricts them from accessing the Chrome Web Store.
  2. A need to control updates.  Automatic updates come with some risk, so many larger installations prefer to control their own updates.  This is especially important if they are controlling the version of Chrome that they deploy since an IE Tab update may rely on features that are in a newer version of Chrome than they have installed.

For these reasons, it is sometimes desirable to install IE Tab from either the local machine or the local intranet.

Local Deployment

For customers who are under a maintenance contract, we provide a service to help them perform local deployments.  This is the recommended approach because other approaches result in a situation where it may be very difficult to update the extension.

The local deployment approach works like this:

  1. You find either an intranet location (e.g. http://internal-server/ietab/) from which to install the extension or a fixed local file system location (file:///C:/ietab_install) where you will use your deployment tools to push the requisite IE Tab deployment files.
  2. You tell us this fixed URL.
  3. We prepare an extension package that can be installed from this location and provide it for you.

We have to provide you with a custom package because the extension file itself (the .CRX file) contains the update URL.

If we don’t provide a custom version of this package for you and you try to install from a local location without an updated CRX file, then you will not be able to update the IE Tab installation because the default CRX file will still try to update the extension from the Chrome Web Store.  So you will either get updates from the store (which you may have been trying to avoid), or if the machine does not have access to the Web Store, you will not be able to update the extension.

Next Steps

Enable Java plugin in Chrome with IE Tab

(Note:  — WINDOWS ONLY — This solution only works on Windows devices)

The Chrome team has removed NPAPI support from Chrome. This means that the Java plugin and the web sites that depend on it will no longer work in Chrome.

But with the IE Tab extension you can still use Chrome with web sites that require Java.

What is IE Tab?

IE Tab is a Chrome extension in use by nearly 3 million users that allows you to use the Internet Explorer rendering engine in a tab in Chrome.

It is typically used for web sites that require Internet Explorer functionality (like ActiveX support). IE Tab allows users to view web sites that require IE without having   to launch Internet Explorer separately.

IE Tab also provides the ability for you to tell it which web sites you need to use IE Tab for and it will automatically open those web sites with IE Tab, providing you with a seamless experience.

How does Java work in IE Tab?

Java works in Internet Explorer using Internet Explorer’s plugin functionality (which is NOT NPAPI).

Since IE Tab supports the same plugin functionality as IE, then as long as Java works in IE then it will work in IE Tab on the same machine.

Okay, show me how!

1. Install the IE Tab extension from the Chrome Web Store:

2. Once installed, click on the IE Tab icon.

3. Install the IE Tab Helper.

When you click on the IE Tab icon, you will be prompted to install the IE Tab Helper.

The IE Tab Helper application is a separate application that is used by the IE  Tab extension. The helper application is necessary to load the IE rendering  engine since that type of functionality is not otherwise available to  extensions.

4. Go to the web site that uses Java.

5. Click on the IE Tab icon to load the page in IE Tab.

You now have the site running in Chrome with IE Tab!

6. Right-click on the IE Tab icon and select Options.

7. Enter an Auto URL for the web site that uses Java.

Now whenever you visit that web site it will automatically open in IE Tab without you  having to click on the IE Tab icon.

Enterprise Customers

You can deploy IE Tab to your users and pre-configure the Auto URLs so your Java applications will “just work” without your users having to do anything.

You will need to purchase licenses for your users (IE Tab requires a license for business use).  For smaller deployments  you can see our current price sheet and purchase your licenses here:
