Questions and answers
How does the free trial work?
Download the app for Mac or Windows and use everything for 7 days from the first time you open it, no card and no sign-up. After that it asks you to buy.
How do I buy and activate it?
In the app choose Buy a Licence (on the Mac in the RR DICOM Viewer menu, on Windows in Help), or Buy when the trial ends. Your browser opens this website with your computer filled in; pay with UPI, card or netbanking through Razorpay in India, or PayPal elsewhere, and the app activates itself within seconds. There is no key to type, and it works offline afterwards.
How many computers can I use it on?
A licence is for life on the one computer you bought it on, Mac or Windows; buy one for each computer. If you replace your computer, write to us with the device code shown in About and we move your licence.
Are my scans uploaded anywhere?
No. Scans are read on your computer and reports are kept in the app. The only thing the app sends to this website is a code for your computer, to check the licence and the trial.
Which PACS does it work with?
Any PACS that allows DICOM query/retrieve (C-FIND with C-GET or C-MOVE), such as most hospital PACS, Orthanc, dcm4chee and Conquest, and any PACS with DICOMweb. You add the PACS address, port and AE titles once.
