The dialog will have 77*cdf0e10cSrcweir "OK" (replace) preselected if x < y, and "Cancel" otherwise. 78*cdf0e10cSrcweir 79*cdf0e10cSrcweir- If replacing an installed version x of an extension e with a version y fails 80*cdf0e10cSrcweir because y has unsatisfied dependencies, or because y has a license to wich the 81*cdf0e10cSrcweir user does not agree, version x is left installed afterwards. 82*cdf0e10cSrcweir 83*cdf0e10cSrcweir- Checking for already installed versions of an extension is only done within a 84*cdf0e10cSrcweir single layer (unopkg versus unopkg --shared; "My Packages" versus 85*cdf0e10cSrcweir "OpenOffice Packages" in unopkg gui/soffice), not across layers. 86
