error: linking mysql tables (odbc) from ms-access: "Could not find installable ISAM"

[tele programador]

I have been connecting to mysql tables from ms-access vba through odbc [MySQL]
[ODBC 3.51 Driver] connection string and everything is ok.

when I try to link mysql tables from ms-access > file > get
external data > ODBC > user dsn, I get: “ODBC call failed” error.

when I try to link from ms-access VBA ADOX, I get: "Could not find
installable ISAM".

I found http://support.microsoft.com/kb/209805/EN-US/ article
attributing error cause to unregistered dll, I have followed the 2 recipes
but nothing happened.

The article above says: ISAM drivers are used by Access to update file
formats other than its own. If the path of the ISAM driver in your
Windows Registry is not valid, or if the ISAM driver does not exist,
the problem may occur.

my question is: what exactly dll (name) ms-access is asking for and
how to register it in order that ms-access can find it the right way or any other valuable information to solve this problem.

Thank you in advance
