If your 64-bit Windows PC generates this error - “Windows Installer Service cannot be accessed and may not be installed correctly” when trying to install some programs, you should first read this Microsoft article. Following the steps in this article is a good way to fix any real underlying problem with the installer service.
But, if you are running a 64-bit version of Windows, you may have a simple registry problem that is preventing the proper use of the installer service even though the installer service is porperly installed. In that case, a simple registry change may be the last remaining step you need to take to get back on track. Note: the following steps involve editing the registry on your PC. If you make a mistake while editing the registry, your machine may no longer boot properly, so don’t try this unless you have backed up your PC!

1. close all running programs
2. Bring up the “run” prompt by holding down the “Windows” key and the letter “R” at the same time.
3. Go to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/MSIServer and right-click on WOW64
4. select “Modify” and change the Value data from “1″ to “0″
5. close regedit and re-boot the computer

Now try and re-install the programs you were having trouble with before.

If your Mac’s fan seems to run constantly, is very very loud, and seems really hot, you should probably have it serviced. However, occasionally some Macs are afflicted with a loud fan noise for no apparent reason. The fan runs and runs very noisily, blowing cool air. This is most probably just a glitch and you may be able to fix it yourself quite easily.

To attempt this quick fix, shut the Mac down, and then unplug it from the wall AC power. If it is a Macbook with a removable battery, remove the battery. Wait five minutes and re-attached everything. If you’re lucky, the fan problem may now be fixed! If that does not work, you may need a firmware update from Apple in order to fix the problem. Go to this Apple page and see if they have an update for you.

  HKLM\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc

Double-click on the name

  “Allow Uninstall”

and set the value to 1. You should now be able to uninstall Trend Micro without being prompted for a password.

Your BlackBerry contains lots of useful business and personal information - that’s why you bought one. But if your BlackBerry is lost or stolen, that information could be compromised. If you have a corporate BlackBerry connected to a Blackberry Enterprise Server (BES), your IT folks will almost certainly use its Remote Wipe feature to nuke your BlackBerry remotely in the event that it is reported lost or stolen. If your BlackBerry is not connected to a corporate Blackberry Enterprise Server, you can accomplish the same thing with a little $9.95 BlackBerry App from roblock.

Once this app is installed, you have a number of theft recovery features available remotely should your phone be lost or stolen. You can track it by GPS or cell tower location, can cause it to emit a high-pitched alarm, can disable it, or wipe it. There are also remote backup options available for a monthly fee.

Each individual toolbar might be nice, but you can definitely have too much of a good thing. Multiple toolbars can slow down your web browsing, cause your computer to become unstable, and even make it hard to see all of a web page on the screen at one time. How do folks end up with so many toolbars?

Is your home in a flood hazard area? FEMA has online resources which outline the extent of the officially calculated hazard areas. One such resource is FEMA’s National Flood Hazard Layer for Google Earth.

An older Windows XP system can sometimes get into a state where complex software products do not install and uninstall properly. One thing to try when you have this situation is to make sure your XP system has the latest version of the Windows Installer. Microsoft has a KB article which describes the 4.5 version of the installer.

The downloads for various flavors of Windows can be obtained directly from Microsoft. Upgrading your Installer will ensure that you have the latest Microsoft fixes for the Installer component, and may possibly fix registry permission issues that are hampering some of your current attempts at installing third-party software packages.
