Error -7041

InstallShield 2026

Message

Could not create instance of CABEngine. CABEngine component might not be installed or registered properly. You may need to reinstall InstallShield.

Troubleshooting Information

To resolve the problem, manually register the file MediaBuild40.dll (in the InstallShield\MediaBuild folder of your build machine’s common files folder) using Regsvr32.exe (in the Windows system folder), using a DOS command line like the following:

Regsvr32.exe "C:\Program Files\Common Files\InstallShield\MediaBuild\MediaBuild40.dll"

Note:This error may appear when an automation script is executed in a Windows Server Core Docker environment that lacks required native Microsoft DLLs. In such environments, InstallShield’s CABEngine COM component cannot be instantiated due to missing or unregistered native components or DLLs. To resolve this issue, see Running an Automation Script via the InstallShield SAB on a Windows Server Core Docker Image (KB article).
