When I will deploy a Setup I get follow error message.
ISMsiServerStartup Failure, Falied to create InstallDriver, Error = 0x80070005
It is a vendor setup an I made some changes with a .mst File.
When I start the Setup with a doubel click or I deploy it with the current user account not with a admin account then it works fine
but the current user have not enough permission to install a software.
