Very nicely done. This is a great way to tell how old the installation is.

I've having a problem with the execution on a SQL2005 (only tested one server). I get the installation dates but before it's displayed I get the following errors

RegOpenKeyEx() returned error 2, 'The system cannot find the file specified.'

Msg 22001, Level 1, State 1

RegOpenKeyEx() returned error 2, 'The system cannot find the file specified.'

Msg 22001, Level 1, State 1

ServerName

My server is a x64 and has several instances installed onto it.

Comments?
