Hi as i was so happy about your support right now, i went through the list of software that we are using at all.
and i found another software that could be of interest, as its used by many people (at least in our company) and its freeware.
Autodesks DWG True View, is comming up at least once a year with a complete new version.
Due to Autodesk changes file types every now and than, it would be optimal to be up to date with the viewer as well.
there must be an .msi installer as i found following command for silent installations.
msiexec /i "<path>\DWGViewr.MSI" /quiet
Thank you for investigating.
This one we likely won't be able to add. It doesn't remove the previous version and it's one release a year. This would be a better fit for a regular app in SCCM.
