ORA-06413 after upgrading Windows 7

SEE ATTACHMENT

I get the above error, after upgrading to Windows 7 and reinstalling
Toad. Any pointers to this ? Pls. note, I installed Toad first and then
reinstalled Oracle Client.
Looks remarkably like ORACLE_HOME is not set correctly, or the registry
setting for this oracle install, is not correct. Did you f=give the
install the same oracle home name or a new one? Did you manage to "hose"
the entire previous install before re0installing? Etc.

The message implies that an error occurred, ORA-06413 and when Oracle
tried to retrieve the message in your local language, it failed.

Check:

ORACLE_HOME
NLS_LANG

Both as environment variables or in the registry settings for this
latest installation.

Cheers,
