Summary

This article explains cause and resolution to error -1027, for InstallShield 2011 users.

Symptoms

ISDEV : fatal error -1027: Failed signing <Installation Package File Name>

Cause

This problem is due to an issue introduced with InstallShield 2010 involving how the Certificate Password field entered in the Media->Releases view "Signing" tab is being stored in the project file.

Resolution

1. Download the attached hot fix .zip file to a temporary location.
2. Exit the InstallShield 2011 IDE.
3. Locate the InstallShield 2011 System folder, <ISProductFolder>\System. By default, this file is located at "C:\Program Files\InstallShield\2011\System".
4. Create a back up copy of file IsWsBuild.ocx
5. Extract the IsWsBuild.ocx file contained in the IsWsBuild.zip file (in the Attachment section) to the InstallShield 2011 System folder located in step 3.
6. Open the project in InstallShield 2011.
7. Go the the Media->Release view. Clone the original release that failed to build. Alternatively, you may delete the existing release and create a new release as well.
8. Under the 'Signing" tab, re-define the Digital Certificate and re-enter the Certificate password. Build the new Release to apply the changes.

Workaround

1. Create the project in InstallShield 2010.
2. Go the Media->Releases view, create a new Product Configuration and Release. Under the Release "Signing" tab, enter the Digital Certificate information.
