Distributing VC++ Redist... running installer when already installed causes problems
installation, visual-c++, visual-c++-installer
Solution
Try the /q flag http://support.microsoft.com/kb/227091 (assuming you're installing it via calling msiexec.exe on their redistributable)
Problem
Using the Inno installer, we distribute the VC++ redistributable with our app so we can run it automatically. We've found that running it on a system where it's already installed asks us to repair/undo the installation which is going to totally confuse users. Is there a way around this? Maybe a flag on the installer or something? Thanks.
