Cannot install SQLExpress after uninstalling June CTP

I try to install SQL Server Express after uninstalling its beta and get the following error in the log file. Can anyone help me? Thanks.

Here's the problem:

You can uninstall this from the command line using the following command:

msiexec /x {2AFFFDD7-ED85-4A90-8C52-5DA9EBDC9B8F}

I get the following error when I execute the command msiexec /x {2AFFFDD7-ED85-4A90-8C52-5DA9EBDC9B8F}

Thanks,

|||Different server, same error message though on trying to uninstall.|||Yep, me too. Exactly the same problem as you guys. How do we get rid of the wretched thing?|||

I am not sure if the following will work in your case, but that work in my case finally:

1. Delete all directories related to the previous version of SQL Server.

2. Search and deleted all keys(or parent key) of 2AFFFDD7-ED85-4A90-8C52-5DA9EBDC9B8F(in my case).

After that, I successfully install SQL Server Express.

That seems to have worked for me too.

Many thanks for your help.
