Problem in upgrade of update manager 5.5.0 u2d

Hi,

I can't upgrade Update Manager from 5.5.0 u1 to 5.5.0 u2d (maybe it's the same that 5.5.0 u2). The installer start to install after asking the login and failed. I found in the release note of Update Manger u2 that install it on a host that have a SQL Server 2008 R2 SP2 may be a problem. I also have a Backup Exec Server on this host that use a SQL Server 2008 R2 SP2. My VMware database is on SQL Server 2008 R2 SP1.

Here what i found on the release note:

• Update Manager installer stops responding if you already have Microsoft SQL 2008 R2 SP2 database on your system
  If on the system where you are installing the Update Manager server or the UMDS there is an existing instance of Microsoft SQL 2008 R2 SP2 database, when you attempt to install the Update Manager server or the UMDS if you select the option to install the bundled database (Microsoft SQL Server 2008 R2 Express), the installer stops responding.
  Workaround: To workaround this issue, perform the following steps:
  1. On the machine you are installing the Update Manager server or the UMDS, open a command line interface and type the following command:
     .\redist\SQLEXPR\SQLEXPR_x64_ENU.exe /ACTION=install /IACCEPTSQLSERVERLICENSETERMS /SQLSVCACCOUNT="NT AUTHORITY\SYSTEM" /HIDECONSOLE /FEATURES=SQL /SQLSYSADMINACCOUNTS="BUILTIN\ADMINISTRATORS" /NPENABLED="1" /TCPENABLED="1" /INSTANCENAME=VIM_SQLEXP
  2. Atempt to install the Update Manager server or the UMDS again.

I think the workaround work for new install but do you know what i have to do for an upgrade ?
