After a lot of iterations and (email) discussions with the user, we have come to the below conclusion:
All the SimCenter tools are presently compiled on Windows10 (done by Frank). The stable version, available on DesignSafe and compiled by Frank, works.
So the conclusion is that there seems to be an issue when the software is packaged using Windows8 (done by Ajay). We will instead package, again using Frank's computer with Windows10 and send an updated package.
