My updates are created with DevStudio 9 (InstallScript project) and they are registered on the US Publisher Web Site. The command line option I specified there is "/s". This should make my updates run silently.
When my application checks for updates (using COM API) and detects an update, it starts downloading the update. After that, when I install the update, it fails to install! When I copy the downloaded update (from my temp\{GUID}_35579 folder to another location, or even try to execute it myself in that location, it installs correctly. (Of course I specified the "/s" option myself here also.)
Does someone know what is going on? And have some solutions to solve this problem?
