Summary

This article provides some information on build warning -4354.

Symptoms

When building your project in InstallShield, you may receive the following error...

ISDEV : warning -4354: The build was unable to extract COM information from the file MyDLL.dll in component MyDLL.dll. Please ensure that the file is self-registering and verify that the self-registration process does not fail.

However if you manually register, using regsvr32.exe, the file mentioned in the build warning registers without any problem.

Cause

The 'IsCmdBld.exe' file is the utility used by InstallShield to perform builds. In certain cases, it's possible that the Windows Operating System will not grant 'IsCmdBld.exe' the access it needs to complete certain operations of the build process.

Resolution

If you update the 'IsCmdBld.exe' to run in compatibility mode, this can sometimes resolve the build warning. You can find more about manually changing compatibility settings for a program here.

It has also been seen that 3rd party security applications have blocked COM extraction. To test if this is the case temporarily pause/stop your security software and run the Installshield build again.
