Thanks for your reply. I have no intent of replacing anything. The dlls I am checking for are not ones I made. These are third party libraries the user needs to install outside of my program. And I am not facilitating their install.
All I want to do is check the version numbers of the libraries that are already installed. The problem is I dont know where the libraries are installed to in the filesystem. <-----Original Message-----> >From: Wilson, Phil [[email protected]] >Sent: 5/18/2009 4:40:55 PM >To: [email protected] >Subject: Re: [WiX-users] Checking registered dlls > >This isn't a common problem because everyone just lets the file versioning rules >take care of everything.
