If the MSI is installed per-user, it would be recommended to cache it somewhere in the user's roaming profile (since per-user installations can roam). In the case of per-machine installation, it should be place somewhere outside of all user profiles that only someone with admin privileges can change (to prevent using your software being a vector for an escalation of privilege virus attack). Don't use private\system directories (such as the C:\Installer folder) as those are not managed by you and there is no guarantee that the contents won't be cleaned out underneath you. For this same reason, it is not recommended to cache it in any "temporary" location, such as under %TEMP%. There is some software that has cached MSI files in the "C:\Windows\Downloaded Installations" folder, but that location may be subject to "cleanup" by the disk cleanup tool. Other locations I have seen include under the Common Files folder of the Program Files folder, in a hidden folder of the program's own installation folder, and in custom hidden folders off the system drive's root folder. I'm not sure where burn caches, I would have to look in through the source code, although I believe it is under the control of the UI you add to burn, so it could potentially be anywhere. ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
