Unable to create a temp copy of transform

Attempting to upgrade Windows installer Application ‘s packages.
the MST failed, noticed the following error from the MSI log:

Installation: Unable to create a temp copy of transform,
Note: 1: 2203 2:  3: -2147287037
MainEngineThread is returning 1624


Solution that worked for me:

Change TRANSFORMSSECURE value to 0 in the registry, and try a re-installation
