Appending registry keys when only MSI available?

[Tim]

Hello,

Perhaps this is a n00bie question, but I have an MSI that
unconditionally writes a registry key and now it needs to append the
value if the registry key already exists. Is there an easy (possible)
way to do this with a modfiication to the key value in Orca, or do I
need to regenerate the MSI with WiX or IS? I've done a rudimentary web
search, and it's not clear.

Thanks,
Tim

I assume you mean the msi creates a registry VALUE in a KEY and you
want to change the behaviour to append something to that VALUE.

If so, just find the right entry in the registry table using Orca.

The documentation for that table is at: http://msdn.microsoft.com/en-us/library/aa371168(VS.85).aspx

To append something to a value it has to be prefixed with [~].

Best regards,
