I have created a setup with version number as 2.0.0.0. We have a few folders which will be added into the installed path. When we click the files and folders menu these folders will be listed. Then I right clicked each folder and clicked the properties menu. Then from the properties window I set the "remove folder" options from operations tab. I have selected the option "Remove even if the folder is not empty" also. i.e. the folder will be removed on uninstalling the main exe component even if it is not empty.
My question is related to rollback.
I installed the 2.0 version. Then I created a new setup which has version number 3.0.0.0 and has new product code too. When we try to install 3.0 advanced installer will uninstall 2.0 automatically. So the folders will be removed too. During the installation of 3.0, if some error happens installer will rollback ,right? If so, will the installer return the deleted folder and its contents? Will I get the 2.0 installation back ?
If not, what should I do to return those folders? Please help ASAP
