The application cannot retrieve the version number from the database which appears to be corrupt.
If there are no data flows you need to retain then you could rename the following directory:
%LOCALAPPDATA%/Dataverse/site
(i.e. in your case C:\Users\helalm\AppData\Local\Dataverse\site)
to:
%LOCALAPPDATA%/Dataverse/site-old
and then run the installer again.
