wix generating new upgrade code
问题 My project needs to have the ability to install 2 versions or more simultaneously. as far as i can find, the solution i have found is changing the upgrade code for each build of the installer. however i want to do this automatically. in regular GUID i just use "*" but this won't work for upgradecode. is there a way to generate new upgradecode in every wix prebuild or any other solution? <?xml version="1.0" encoding="utf-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:util=
