Hi,
this message is targeted to XE6 user only: Unfortunately XE6 Update 1 is a breaking update. Our installers are always build against latest IDE/compiler
--> Update 1 for XE6 is a requirement (otherwise you get error messages like "Package dclcommon200.bpl nout found" or similar).
In About-dialog you should see version number as follows for Update 1:
20.0.16277.1276.
Original version is:
20.0.15596.9843
If you want to use latest LMD controls within XE6 without Update 1: Get the source installer and rebuild packages manually.
