not able to roll back to BI4 from BI5

[Neil Sidhu]

installed BI5 to test it out and then decided to uninstall it to wait for some more updates. My BI4 stopped working as in would not open, no errors. I uninstalled BI4, rebooted and installed BI4 again. Same thing, no splash screen or errors. Please tell me i dont need to rebuild?

Plenty of threads on similar issues, have a look and read and hopefully you’ll find an answer.

I've just restored my backup of BI4, its easiest just to uninstall 4/5, clear the registry, then reinstall 4 and restore the Perspective Software reg key, and %ProgramFiles%\Blue Iris 4\ folder from your backup.
