This library is designed to be used with NSIS (Unicode version). It provides the following features:
OBSInstallerUtils::IsProcessRunning
OBSInstallerUtils::IsDLLLoaded
OBSInstallerUtils::AddInUseFileCheck
OBSInstallerUtils::GetAppNameForInUseFiles
OBSInstallerUtils::KillProcess
AddInUseFileCheck expects a full path. Can be called multiple times. Afterwards, call GetAppNameForInUseFiles and $R0 will be a nicely formatted list of applications that are using the specified files.
KillProcess takes a substring match on the full path.
Other functions sets $R0 to 1 if true.
