Silent install: Run the installer, then grab the install files from the temp folder. Run this new setup.exe /r to record a setup.iss file, then copy it from C:\Windows to the same folder as setup.exe. Run setup.exe /s to install. Silent uninstall: The uninstall command in add/remove programs uses rundll32.exe and has no silent switches. I found a couple of other functions in the DK2INST.dll that will do the job silently: [SystemFolder]RunDll32.exe [SystemFolder]DK2INST.dll,DK2INST_DoUnInstall This will uninstall the driver. [SystemFolder]RunDll32.exe [SystemFolder]DK2INST.dll,RunDLL_UnInstall_SelfDelete This will delete DK2INST.dll. Both DK2INST_DoUnInstall and RunDLL_UnInstall_SelfDelete is case-sensitive by the way!
