To uninstall the Sigma Magic software, go to your Control Panel, select the Sigma Magic software, and then click Uninstall.
Clicking on Yes will completely remove the software from your system.
Note that the uninstall software will only remove the software files in the C:\Program Files (x86)\Sigma Magic folder (or your AddData folder) and any registry entries. In addition, any desktop icons and software menus in the Start folder will be removed. It will NOT remove any files you created/saved using the Sigma Magic software.
If you want to use the software again, you must reinstall it on your computer by clicking on the Setup file.
