Virtual Box 2.1 on Windows 7

I couldn't get VMware Workstation 6.5.1 32-bit to install on 32-bit Windows 7 Ultimate.  It just died every time I tried.  Then I tried VirtualPC 2007, same result.  Ugh!

Then I went to run the Virtual Box 2.1 installer (32-bit) and it choked also, but then Windows tossed this bad-boy at me...

Solve a problem with Windows 7 beta

An issue with the Customer Experience Improvement Program (CEIP) client in Windows 7 beta is causing Explorer and some MSI-based installers to stop working properly.

To solve this problem, follow these steps:

1. Click the Start button , click All Programs, and then click Accessories.

2. Right-click Command Prompt, and then click Run as administrator. In the User Account Control window, verify that Program name is Windows Command Processor, and then click Yes.

3. In the Administrator: Command Prompt window, type or paste the following text at the prompt:

   reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f

4. Press Enter to install the solution.

5. If The operation completed successfully displays, close the Administrator: Command Prompt window to complete this procedure. If "ERROR: Access is denied" displays, repeat this procedure from the top, making sure you clicked Run as administrator in step two.

   
   

   It works!  Now, I'm off to try out Virtual Box...

   
   

   EDIT:  I really like Vbox.  The interface is kind of a best-of-breed between what works in VirtualPC 2007 and VMware Player and VMware Workstation.  Sort of.  Very "web 2.0" looking.  I like it.  It also opens .VMDK and .VHD disks without any problem and boots them just fine.  All of my VPC and VMWare guests work fine in it.
