I have 7.8.3 but not vbox on a system that I now want virtual box.

On a system that DID have virtual box, I received a notice that an upgrade was available. I failed to make a note of the version but I recall the upgrade was recommended and it seemed important for security. I looked on that system for the upgrade in "Downloads" but cant find it. Must have been a temp download. I do not wish to re-install boinc 7.8.3 just to get vbox and then have to upgrade plus have to fix items that need to be changed (customized) with that re-install.

I went to the VirtualBox org and they hide the .32 build and want to install 5.2.6 Looking at boinc's repository I see 5.1.26 which is older than 32.

Should I put in the recommended 5.2.6 or that last update for the old builds the 5.1.32 which is not recommended?

[EDIT] I ran the VirtualBox program on that system and it reported 5.2.6 so that must work with boinc. Unaccountably, I have another system that is still at 5.1.26. Strange that I was advised to upgrade only on one system.

I will download the latest and greatest VBOX and see if a separate install works.

[EDIT] Didn't work - Started up LHCathome and got their message from boinc that virtual box was not installed. Seems I will have to install boinc+VB.

OK, it worked after all. I forgot to reboot after install VBOX. So one can download 5.2.6 to add VBOX and reboot to get it to be recognized.
