Hello,
Yes, there seems to be a bug.
When installing a HWD file from the Update Center it's not always visible in GUIDE. Then you can install it manually as
acmall mentioned.
In some cases not even that works, so we have found a workaround.
"The work around is to have PLUS+1 GUIDE closed and navigate to the following directory.
C:\Users\your logon\AppData\Roaming\Danfoss\PLUS1\2022.2\Data\GUIDE\HardwareBookcase
and delete the BookCase.xml.
When PLUS+1 GUIDE 2022.2 is restarted the BookCase.xml will be recreated and updated."
I'm not 100% sure if it helps you, but you can try.
If it doesn't, please report it here:
