I have recently installed SP10 update to Hevacomp however when I try to open a existing Netsys hot or cold water program a run time error 53 occurs, also when trying to create a new hot or cold water sizing file a run time 53 error occurs.
I can open existing gas and ductwork sizing programs but cannot create new projects.
The mechanical designer appears to operate correctly and I can create a new project.
It appears to be just the hot and cold water sizing programs that have the issue.
Please advise
Regards
