Hello,
I built my model in Hevacomp but when I try to run CIBSE calc's a prompt shows up "DDB Program Not Available".
Regards,
Hi Grant,
Thanks for raising this, could you please attach any screengrab of the error message you are seeing?

Please see attached.
Thanks Grant,
I'm guessing this has occured due to an improper installation. Did you install the software recentley? or it was there and it is happening for all the projects?
I would look forward to your response.
The installation is not recent, I've been using it for many projects. This has just suddenly occured.
Thanks,
Lastly, is it happening for this project only? or for aother ones too? If it is a specific to this project, I might ask you share your project so that we can have a deeper look.
Hi Krishnendu,
This seems to be happening for all projects.
I can still modify geometries and rooms but cannot run any calcualtions.
regards
Thanks for the details. If this was working previously until recently I imagine it would have been changes external to the software that have caused this - most likely a Windows update that has increased permissions restrictions on your machine.
A quick test is to close Hevacomp, and then start it by right-clicking on the Hevacomp shortcut and selecting Run as Administrator.
If that does not work I would suggest also lowering User Account Control in your Windows settings, and then trying to run as Admin again.
