[dba-VB] Installing MS SQL 2005 Express on a PC with MS SQL Server 2008 R2 (v.10.50.1600)

Hi All --

Did you ever try to install MS SQL 2005 Express "in parallel" to an MS SQL
2008 R2 (v.10.50.1600) instance already installed on the same PC? It
happened that my Windows hosting provider doesn't support MS SQL 2008 R2
(v.10.50.1600) backups' restore operations, and therefore I have to use MS
SQL 2005 for some of my databases.

Thank you.

P.S. Another option could be to use MS Virtual PC with a test Windows XP
instance and to install MS SQL 2005 on it but I wanted to avoid this
"trouble" if MS SQL 2005 Express could install fine on a PC with MS SQL
2008....
