More than one version installed?

Is it possible to have different versions of LO installed at the same time?
LO 3.6.1.0.2 has a bug that was not present in LO 3.6.0.0.4 and I have to convert my old 123 files and do not want to uninstall the new one.

Installing several versions of LibreOffice in parallel

Thank you manj_K. I just wanted to add a tip that almost through me off in installing a 2.version: You have to open the command prompt as administrator, otherwise you get the error 2203. Might not be nessacary on all win7 installation. The german version of your link is very good.
