Java Not Installed – Fixed in Chrome

Recently we learned that the newest version of Chrome will no longer support an antiquated Netscape API. Basically this disabled Java applications from running within Chrome. As we’re in the midst of mandated State Pearson testing, this break resulted in significant problems for our students.

According to a recent Google Chromium thread this feature is being deprecated totally in September 2015.

In September 2015, Google will remove the override and NPAPI support will be permanently removed from Chrome. Installed extensions that require NPAPI plugins will no longer be able to load those plugins.

There is a simple solution, which is to re-enable the NPAPI plugin. That setting can be found below

Fix Blocked Java

Due to recent security issues Java has changed the way their web plugin functions. However many websites required older, different versions of Java and therefore it is essential to allow these older versions to still run. Below I’ve outlined the steps necessary to allow these older versions access.

First, you must open your Java Control Panel.

Click on the Start Button and type the following: configure

Then, click on the Configure Java shortcut as displayed below.


From this Control Panel you will need to make a change to the Security tab as depicted. Lower the security level to medium. This will allow all java applications to run after the display of a security prompt to confirm.


Windows Desktop – Sound Fix

Just recently I encountered a very random, seemingly odd issue related to sound and a Windows 7 desktop. I initially tested the speakers to ensure they worked and then I took a look at the desktop. The soundcard didn’t seem to be bad, neither was the integrated audio but I still couldn’t get the machine to play sound. After searching around on the Internet for awhile I encountered an easy fix that was mentioned a few times on various sites. The original article can be found here (

Please note that the following process will lower the security of your PC. For corporate customers this isn’t such a big deal but for personal users you want to ensure you have additional forms of security in place before you enabled these settings.

At a secure command prompt please type the following commands.

If you ever want to revert the changes then just run the same commands, swapping delete for the add command to reverse the process.

Google Docs / Drive Firewall Settings

As Jefferson County Schools in Colorado have switched to Google Applications many local schools have some issues with accessing the various Google Applications from behind their firewall or from their location. Google released a document that outlines the various network changes that are necessary in order to allow Google Applications to work at your location.

Google Drive and Sites were designed to work on uninhibited networks. However, for domain and network administrators with specific firewalls and/or servers, the following sites must be accessible for Google Drive and Sites to function properly:

For the following, [N] means any single decimal digit. * means any string not containing a period.

Documents List, Documents, Presentations, and Drawings
http (port 80) connection to, docs[N] and *
https (port 443) connection to and docs[N]
https (port 443) connection to *

http (port 80) connection to,, spreadsheets[N], and *
https (port 443) connection to, and spreadsheets[N]

http (port 80) connection to

https (port 443) connection to
https (port 443) connection to
https (port 443) connection to *
https (port 443) connection to
https (port 443) connection to *

The IP addresses that the various domain names resolve to cannot be assumed to fall inside any given address range. IP addresses used by Google Drive may be used by other Google properties. The techniques that Google Drive uses to connect to Google servers depend on the browser, browser version, and networking conditions, among other things. Even if activity to some of the addresses above is not observed in a particular Google Drive product, that doesn’t mean it never will be.

Windows 7 Print Spooler Error Fix

The guide below demonstrates a simple fix for common Windows 7 print spool errors. If the print spooler error persists after troubleshooting there may be additional corruption within your OS or printer driver subsystem. As always, make sure you are using the most updated drivers available from your manufacturers website.


1] To begin, open up services.msc and STOP the print spooler service

2] Browse to c:\windows\system32\spool\PRINTERS using Windows Explorer
(If prompted by UAC click yes to approve opening the PRINTERS folder)

3] Delete ALL of the files located in the PRINTERS folder and then you can close Windows Explorer.

WARNING – Do NOT delete the PRINTERS folder itself

4] To finish, re-open services.msc and START the print spooler service

Dell D630/D830 Windows 7 64-bit Touchpad Drivers

Ran into an odd issue after installing SP1 for Windows 7 x64 on a Dell D630, the touchpad / pointing stick stopped responding.

Looking at driver download page for the D630 / D830 (Windows Vista 64-bit) on Dell’s support site shows there are no drivers provided for the touchpad / pointing stick.

I find the lack of updated drivers to be a common problem with Dell’s support site, the solution is usually very simple – look for a similar model system with the correct drivers. In this case the driver page for the D430 provides us with a 64-bit install package for the Dell touchpad / pointing stick.

You can go to Dell’s support site here and download it. Or you can also download it here:
