Hello,
Which version of RealityCapture do you have?
Here are some fixes for this:
FIX 1:
Uninstall the older version of RealityCapture, and make sure that everything connected to that version is being removed (even from the registry).
FIX 2:
Remove the device from the Domain Controller and uninstall it and remove it from the registry, after new installation and online activation it may work.
The time may be a problem because it can be managed by the organization and I can be different from the official time in 1 sec approx.
FIX 3:
Make it like a clean install (hold CTRL + Shift and run RC, then choose to “Make it like a clean install”) and use Offline activation.
FIX 4:
Check if RCNode.exe is blocked by the system firewall. Then go to RC install folder and start RCNode - Windows shows firewall notification and accept it for all networks. Additionally, you can start RC as admin and in general settings do license change → application owner resign in, also charge for offline use sign in again.
FIX 5:
This issue might be connected to some really old files located in the C:\Program Files\Capturing Reality
Please try to uninstall RealityCapture then head to C:\Program Files\Capturing Reality and delete everything you will find about RealityCapture also in ProgramData, AppData, and Windows registry. Then restart your PC and try to install RealityCapture again and run the same test.
FIX 6:
Rebooting (and allowing Windows to apply an update) cleared this in my case.
FIX 7:
Make sure that your Windows OS is legit, and that it was installed properly.
