I have created windows installer application, now when I upgrade the same I get following error “Another version of the product is already installed. Installation of this version cannot continue. To configure or remove the existing version ...use add remove program in control panel”.
it appears that if a version number is less than 1, removePreviousVersion won't work...I changed my version number to 1.x.x.x (changing product code and keeping version code the same) and it works great.
