hi all, I have a list of 40 files as patch (*.prz) and need to upgrade these for every new computer. The procedure for upgrading requires I copy a patch upgrade from source folderA (C:\) to folderB (E:\), then I run the update from my application. When the upgrade is finished, the folderB is empty and the next patch is pasted in and run. It must do one by one and I hope VBA can help me in this case. I'm thinking of using Microsoft Runtime Scripting and FSO but not sure. Thanks for all the help.
