After you install RTM_Layout on your Windows PC, be sure to grant it Administrator rights. If you don't, it will likely fail when you take Snapshots or try to create a new Project file.
The reason is Windows blocks the App because it doesn't have Administrator rights. Unless you grant those rights, the software can't create (or even delete) certain files.
To get around this, right click the on your desktop. From the dropdown, choose the 'Compatibility' Tab. Then check "Run this file as an Administrator".
Now RTM_Layout won't be blocked by Windows file security issues. All should run smoothly.
