Hello everyone,
I am just experimenting with patches. I've successfully created a project where the V1.0.0 installer installs two .txt files, and the V1.0.0 -> V1.0.1 patch changes one of the text files, leaves the second as it is, and adds a third one.
However, after applying the patch, I can't uninstall the program using either the V1.0.0 installer or the V1.0.1 installer. Both give me the error message "Another version of this product is already installed. Installation of this version cannot continue etc. " and I have to manually uninstall it from the Control Panel.
How can I fix this? I remember most professional products having an uninstaller that successfully uninstalls the project no matter which patch is applied. I'd like to include something like this in my project as well.
Thanks in advance,
Kira Resari
