Re: Ask for install or update during setup

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Hi Ken,
I created new upgrade as described in the article you linked to. However,
when I try to upgrade on another machine, it comes back with:
"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 program on the Control Panel."

Any idea?
Thank you for your reply.
