Activation limits

Hello,

I'm a proud Radiant user (a single pernament license). I'm one of those guys who use virtual PC's (mulitple), 2 laptops, wine in Linux and other stuff.

A few simple questions:
1. How often I can activate Radiant using the same license? I've read somewhere that 90 days (so ~4 times a year).

2. Is there any limit of activation-deactivation cycles? I've recently lost my pernament license for a software that allowed deactivation but it did NOT let me activate once again. (Philips ProDictate). Do You plan to implement such a limit?

3. Does the same limit (regarding time between activations and possible acivation-deactivation cycles) apply for a subscription-based license?

4. Is it counted other way if I activate multiple times on the "same PC"? I've read somewhere here that I can activate twice on the same PC. Is it twice in general, or twice in the 90-day period without resetting the counter?

I'm trying to plan how to efficiently use my license and how many additional subscription-based I could need. I'm really afraid of losing my license (or being unable to reactivate license-based one) while playing with wine of virtual machines, as I purge them from time to time (both wine and VMs).

Hi boskar,

Thank you for supporting RadiAnt and purchasing the license.
There is some info about activations here: https://www.radiantviewer.com/dicom-viewer-manual/activation.html

1) Yes, a license can be moved to another PC only after 90 days passed since last deactivation.
2) There is a limit preventing more than 2 deactivations on the same computer.
3) Yes, the above limits are the same for subscription licenses.
4) This question is answered in 2)
5) If there is an "emergency" and the customer cannot deactivate the license because of the limit we are always willing to manually release the license (unless there is some clear abuse attempt, which is almost always not the case).

6) (ad 2) Are there any limits in deactivation on _different_ machines? Especially regarding my current virtualised approach.

7) Can I activate again after purging wine environment (effectively "formatting C:\ drive") without prior deactivation? Will it affect the "deactivation counter"?

I totally understand Your worries about abusing a single license on multiple computers, although... You know, I'm just a nerd trying to get the most of my Linux host. I try to experiment with the trial, but at some point i give a break to my experiments I try to use Radiant for a month or two, wine gives me better performance and some bugs, windows 10 virtual machine is performing worse but is more stable, and the best way to play/debug is to always start with a clean environment.

6) No, only 90 days pause between deactivations.
7) If the hardware ID and the host name does not change, then it should be possible.

You should not worry about loosing your license. At worst case, you will have to drop us a line a we'll release your license ;-)

Sudden loss of PACS functionality can only be attributed to some issues with the local network connection or the PACS server.
