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 etc.. MainEngineThread is returning 1624
Solution that worked for me:
Change TRANSFORMSSECURE value to 0 in the registry, and try a re-installation
