I've retyped some of the lines thinking a hidden char might be the issue, but to no avail.

Thanks again!

Use the function to retrieve the Product Key from the local PC:

Get-SQLserverKey

2008 server has a different registry, I get a binary result. I am not sure if this is even the CD Key, I wasn’t able to find the CD key for 2008.

Error msg .

Is there any way of reading the regstry & getting to knw the SQL Server Instacnes on the particular box along with the version (2000 Or 2005)

Thanks

I want to trap above error without using TRY..CATCH. So that It can support to SQL Server 2000 also

Thanx in advance!! chief

Also i need to know how to retrieve the Sql server Instance Name from the Registry.
I am using SQL Server2005 Express version.
Thanks

BTW, when I cut and paste the code above, it uses ‘ (acute quotes) instead of ' which messed me up briefly.
