I normally leave the last 2 packages and delete the oldest when I add a new one. I rename my flash MSI to include the version number and active x or plugin, then edit the GPO to add the new package so it upgrades the previous version. It does cost $$$ but we've found it to be VERY worth it's price. This takes all the leg work out of the push installation method and ensures that the software is upgraded as it was originally designed. One last thing I'll mention, we bit the bullet and finally purchased Ninite Opens a new window to install all of our "free" applications that we put on all computers. If I didn't have VirtualBox.well, I'd rather not think about that!!! If you don't have a virtual testing environment you'd do yourself a favor in looking in to it. My last workstation I made sure to have 16gb of ram and installed Oracle's VirtualBox Opens a new window to setup and run my testing environments. It is paramount in making sure it doesn't actually cause you MORE work in the long run with all the cleanup to fix the extra problems. I can't tell you how many times I've been bitten by not testing. When deploying software, the key to making sure that it works as advertised is by testing, testing, and more testing. Removing the application from the GPO without telling it to "remove." caused problems as well. Replacing the old installer files with the newer ones and "redeploying" never worked damaged the installation. I found that if I didn't do exactly this, then there was something that wouldn't behave correctly and would either not work or damage the installation. Then create a new application with the newer MSI installer file and add any additional transform files, etc.īy doing this, upon reboot of the computer it will uninstall the application, then install the newer version in that order prior to showing the Windows login screen. Right click on the application->All tasks->remove Opened the GPO and navigate to Computer Config->Policies->Software installation What I've found through testing is that, at least for this app, the best way to go about this is to remove, then re-install the software. I've recently been entrenched in upgrading an MSI-based app and have been using a GPO to push out the application.
