I am new to LRTimelapse and need to know if I have to uninstall v 5.0.4 to be able to install v 5.0.5 correctly.  It says to uninstall version 4 before installing 5.0.5 but it doesn't say if you need to uninstall version 5.0.4 or not.

Any help would be appreciated.

Thanks.

No, you don't need to uninstall the previous 5.x version - just install the new one.
