Dopus 12.10.3 (Beta) 3 error

having updated to [12.10.3 (Beta)] i get an error after a restart on win10 1803

Opus appears to have installed, but this is what awaits me when i log on

Error Code: -5001 : 0x8000ffff
Error Information:

SetupNew\setup.cpp (473)
PAPP:Directory Opus
PVENDOR:GPSoftware (www.gpsoft.com.au)
PGUID:0A6AA615-5321-43A0-AFAE-97BF95013EA0
$18.0.329
@Windows 7 / Server 2008 R2 Service Pack 0 (9200)
IE Version: 9.11.17134.0

Is that the full error message or is there more?

Could you post a screenshot of the message so we can see the style of message box? That sometimes clarifies where the message is coming from.

It looks like something to do with the installer rather than Opus itself, so you may find reinstalling and rebooting resolves it. Check the installer's digital signature to make sure it was not only partially downloaded or anything like that:

Antivirus can also block parts of the installer or make it crash. Check your antivirus software's logs in case they indicate anything is happening.

The second-last suggestion in this guide may be worth trying, if still having problems:

yes that was all of the error, which i do suspect is the installer as DOpus is working.

i did try another reinstall and reboot but the error was still there

nothing appears to be wrong with the digital signature

i've downloaded the installer again so will report back

this was the error got, i re-installed but still get this after a restart. after a shutdown, the error doesn't appear, so may be just a one off
