  • Installed - on return contains true if the module has been installed or false otherwise.

Description

Use this method to get information about the installed driver or helper DLL. Use Module parameter to specify, which module (driver itself or one of the helper DLLs) should be installed.

ProductName is used to distinguish between installations of the package made by different applications and to prevent the situation when the package is installed by two applications and further deinstallation of one of them removes the package.

FileVersionHigh and FileVersionLow both contain two values - one in the upper 16 bits and the other in the lower 16 bits.
For example for 2.32.6.28

FileVersionHigh - 0x00020020 = "2.32"
FileVersionLow - 0x0006001C = "6.28"
