Hi @shikha525 ,   The mentioned merge-module has to be added to your project to get rid of that error.It can be done either By adding/checking specified merge-module in redistributables view APPLICATION DATA->Redistributables if it is IDE build Or If it is a build machine/server which makes use of only IsCmdBuild,the specified mergemodule path can be passed as commandline with "-o " -o <merge module search path> Basic MSI, InstallScript, InstallScript MSI This parameter specifies one or more comma-delimited folders that contain the merge module files (.msm) that are referenced by your project. InstallShield   provides additional ways for specifying the folders that contain merge modules. For more information, see   Specifying the Directories that Contain Merge Modules .   Thanks, Jenifer ... View more
