Using Windows 7 & Server 2008 R2’s Compatibility Mode

  • Article

If you are like us, we are always on the cutting edge (what do you expect – we work for Microsoft <g>) and because of this we have to often find unusual methods to work around the fact that OEM’s are not always “up to speed” and releasing installers and such that are for operating systems that are still in beta.

Because of this, many of you might find yourself scratching your head when you attempt to update your client or server hardware using the OEMs installation file (*.msi or *.exe).  In this post, I want to share a couple of examples of where I was able to successfully get around this using a pretty “unknown” piece of functionality in Windows 7 or Server 2008 R2.

Let’s get some Background here first

Windows Vista implemented the first version of User Account Control (or limited administrator) functionality that has gotten rave reviews since its release (the tone here is missing).  As much as we hate it, the feature is one that can save your bacon (or rear end) if you are a standard user.  Beyond that, limited administrator can also make your life miserable as you attempt to run installers who are written in such as way that they expect to run as a user who has a full administrator token.  This isn’t the case with Windows Vista or the upcoming Windows 7.

You have a user account, let’s say Chris, that is a member of the local machine’s administrators group.  However, this account is not the actual user named ‘administrator’ and thus your administrative privileges are not included as part of your standard token when running 99% of the time.  However, if you attempt to do something such as install a device driver that requires administrative privileges then the system prompts you asking you to elevate.  You have two choices – Allow or Disallow.

Installation Failures:  Always try Compatibility Mode

Until released, there are a great deal of OEMs who will not officially support Windows 7 as they are in “testing” mode.  Thus, you are unable to access bits that are natively targeted at Windows 7 client or server.  This creates a little bit of a quandry for you if you have a need to update a server with an application that doesn’t natively support Windows 7.

The nice thing is that the security model for Windows 7 hasn’t changed drastically from Windows Vista.  The key word is drastically and for the most part you will not fail if you attempt to push a Windows Vista installation on a system that is running Windows 7.

Recently, I had the need to install a Support tool to obtain information about one our SAN-connected hosts.  The program was provided to me by EMC.  I ran the tool on the server and what I received was the following:

The other scenario we saw this was with Dell downloadable Windows applications that will update driver hardware.

Using Compatibility in Windows 7 & Server 2008 R2

To workaround issues such as those outlined, you can use the compatibility mode available in Windows 7 & Server 2008 (it was also in Vista but I haven’t tested it as much <g>)

To use compatibility, do the following:

  1. Right-click on the file in questionimage
  2. Click the Compatibility Tabimage
  3. Click Run this program in Compatibility mode for:image
  4. Select the Operating System that the installer package is supported for, such as Windows XP (Service Pack 3)
  5. For Privilege Level, check Run this program as an administrator
  6. Click Ok
  7. Execute the installer file by double-clicking

The installation or setup should now run and execute as the system is now running in compatibility mode.

Enjoy!
