Effective with Sage 2013 ERP, I know that you can install only once copy of 2013 on a machine. With the release of Sage 2014 ERP, I successfully installed it on my server in a parallel installation so that I could test and play. All is cool and works well at the server. Unfortunately when I tried to do a workstation install, I got : "Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel." My research so far has turned up nothing about this. This would be a death knell for doing a parallel upgrade and doing proper due diligence testing before going live. Normally during a test upgrade, you need access to both the old and new version of the software. Test in the new, continue to do live work in the old. Anyone know anything that I haven't found yet. Have a hard time believing that this could have been missed in testing.
