Hi,
I have a product1, from my company, installed on some computer. Now my
company makes a new product2 and wants to install it on the same machine
(where product1 exists), but the condition is that the product1 should be
first uninstalled. The requirement is that the uninstall cant happen as a
separate user experience. The product2 installer should start and in the
"/qn" mode uninstalls the product1 and continue with the installation of
product2.
I looked at the forum posts and was thinking of one solution. What I thought
is that on the product2 installer screen where the text "click next to begin
installation", I somehow call a dll's function and execute
"C:\Windows\system32\msiexec.exe /x {product1guid} /qn" in c++ code when the
Next button is clicked. Once this action is done the product2 installation
can continue. Is this a nice idea ? And can this be done without having to
write this c++ dll function?
Please guide.
regards,
..ab
