TallyEZ application is installed using the Pool Service installer as described in the Salesware Installation Guide. If you are adding TallyMan module to an existing installation, you can simply go to Start > Control Panel > Add or Remove Programs on your middleware server and re-invoke the Siriusware Pool Service installer with the Change option. You can then select the Modify radio button and install TallyEZ Pool Service and (optionally) TallyEZ Training Mode. You must also download the TallyEZ_xxxx.exe update file from the Siriusware Information Portal and place it in your updates folder before you invoke TallyEZ application for the first time.
