Mysql ODBC driver 5.1

[GiorgosI]

Plesk 9.5.5
Windows 2008 R2 SP1(x64)

Plesk 9.5.5 installs Mysql ODBC driver 3.51(32bit version I think). We would like to install Mysql ODBC driver 5.1 without uninstalling 3.51 version, because a lot of sites already use the 3.51 driver.

Does anyone know if 3.51 version will continue to exist and function correctly, If I install the 5.1 version on the same server?
Should I install the 32bit or the 64bit of 5.1 version?

Thank you

If anybody has the same question, I installed Mysql ODBC driver 5.1 x64.
Mysql ODBC driver 3.51 remained installed and all sites using it had no problem.
So, there is no problem installing Mysql ODBC driver 5.1 in Plesk servers having already installed Mysql ODBC driver 3.51.
