There is one "gotcha" here. If you install in Program Files the AppData folder gets written to differently. For instance, installing Omnis outside of Program Files, it will add a ...\TigerLogic\... Folder in the AppData folder while installing it within the Program Files folder does not have the TigerLogic folder.
