Trouble installing HL7 Accelerator on BizTalk 2009?

Folks, If you are installing an earlier version of HL7 Accelerator on BizTalk 2009, you will probably reach upto the name of the DB (default BTAHL7) and on clicking next it would just sit there and do nothing. You need to install the BizTalk 2009 Accelerators for HL7 and now you're cooking with gas!
