Title
Build Error -6058 or Build unable to distinguish between 32-bit and 64-bit merge modules

Summary

The build process attempts to locate dependencies in all Merge Modules in the InstallShield Merge Module search path. The 64-bit and 32-bit file names are identical, which may result in the first Merge Module containing the file being selected, regardless of platform.

Symptoms

(A) Build of an InstallShield project fails with Error -6058.

(B) Primary Output includes a dependency on a merge module. At build the incorrect version of the merge module is included in build.

For example the build log may indicate:

Adding merge module 'XXX (x64)' that is a dependency of component 'YYY.Primary_Output'
Merging XXX (x64): C:\Program Files\Common Files\Merge Modules\XXX_x64.msm

(C) The issue with an incorrect merge module at build also exposes itself with the following error in a build log:
ISDEV : error -5008: Intel64 or AMD64 must be specified in the template of the Summary Stream

In the event you experience error -5008 and you do not expect or specified to build a 64Bit installer package apply the hotfix with instructions described below.


Cause

The build process attempts to locate dependencies in all Merge Modules in the InstallShield Merge Module search path. The 64-bit and 32-bit file names are identical, which may result in the first Merge Module containing the file being selected, regardless of platform.

Resolution

The fix can be applied according to these steps:
1. Verify InstallShield 2010 Service Pack 1 (see Q206429 in Related KB Articles section) and InstallShield Expansion Pack (see Q209084 in Related KB Articles section) have been installed.
2. Close InstallShield.
3. Close Visual Studio if appropriate.
4. Download the hot fix 'Hotfix_6058.zip' from the attachment section of this article, and uncompress the files into a temporary location.
5. Locate the folder: <InstallShield Install Directory>\System. (By default, this directory is "C:\Program Files\InstallShield\2010\System")
6. Make a backup copy of file IsMMUpdater2.dll.
7. Copy the new IsMMUpdater2.dll file to <InstallShield Install Directory>\System.
8. Locate the folder: <InstallShield Install Directory>\Support. (By default, this directory is "C:\Program Files\InstallShield\2010\Support")
9. Copy the new PlatformFilesToModules.ini file to <InstallShield Install Directory>\Support\PlatformFilesToModules.ini.
10. Rebuild the InstallShield project.
