OSID Generator returns invalid (not recognised) GUID

Hi All,

I'm trying to figure out how we can silently uninstall our AIR app.  I created a very simple app to test this.  I built the AIR file with a self signed cert.

I plugged in the following 2 items to the OSID Generator

Application ID : windows

taken fromdeployed application.xml

<!-- The application identifier string, unique to this application. Required. -->

<id>windows</id>

and it spits out

Windows GUID : {02872030-9873-8295-8E33-2B21D3C9837A}

However, when i try to execute

c:\> msiexec /x {02872030-9873-8295-8E33-2B21D3C9837A}

I get the following error

What could possibly be going wrong ?  What should I do next to try to figure out why it's not working?

Thanks in advance....
