Hello Marc,
You are probably using Windows Vista and higher, you have installed Swisslog in the Program Files folder and you installed the previous version of Swisslog without disabling UAC nor installing as administrator as clearly indicated in the first screen of the installer. This causes that you are not working in C:\Program Files\Swisslog but in another system folder (VirtualStore) and the new version has not been able to update your real working files.
Please read this thread I posted in the forum where I explain all this and the solution:
