Not enough disk space

‘Not euough disk space’ message from some PC when installing Spark 2.7.0

I have been using Openfire 3.10.0

Downgraded to 3.9.3 and everything is fine.

Are you saying that after downgrading to Openfire 3.9.3 you are now able to install Spark 2.7.0 those PCs? Spark and Openfire shouldn’t be related in this case.
