Dear Peter,
ivsEdits is a mature and stable software and it is used by thousends of professional editors, all over the world. You may see from the requirements page, Windows 10 is not yet on the supported OS list http://www.ivsedits.com/default/system-requirements.aspx
Have you read the requirements before installing the software? Is the OS the only unsupported PC spec?
Best Regards,
Paolo
P.S. There will be soon new releases both of ivsEdits and Windows 10, and requirements may change quickly :-)
