Is it possible to prevent SourceTree from crashing when it can't access the Windows Registry?

[Charles Wilson]

SourceTree 1.9.6.1 is currently crashing on my machine after startup. I'm running Windows 8 with McAfee installed (by corporate IT). I googled the error, and found this issue reported: https://jira.atlassian.com/browse/SRCTREEWIN-5481.. However, there's no workaround or fix info attached to the issue. Has anyone experienced and/or resolved this issue? Why does SourceTree need to change registry values? Can that be prevented?

I think that Atlassian staff would have to answer your question about what it's trying to write to the registry. Maybe @Jesse Yowell or @Gideon Koh? I can't seem to tag Kieran Senior or Michael Minns.
