cannot update to 5.54.7088

Been using cc professional for years with no problems. This is the first ever issue, it downloads then says "error opening file for writing" half way through. Any suggestions? running windows 10, cache clear, all temp files cleaned, 1 year old hp laptop

See if anything in this topic helps:
