I re-installed 4.2b SR-1 on Desktop via Method 3 (actually used Logos4.msi to install) and soon began to notice discrepancies with the metadata.
Type                             Desktop      Laptop
type:commentary             308             301
type:Notes                         10                12
type:encyclopedia             11                32
type:lexicon                        7                 25
type:dictionary                   42                 3
This metadata does not reflect the re-classification of type:dictionary.
 
Example resources with Type:
Title                                                         Desktop           Laptop
Apologetics Study Bible                          Commentary      Notes
Believer's Study Bible                             Commentary      Notes
You Can understand the Bible Seminar  Commentary     Monograph
Treasury of Scripture Knowledge            Notes                Cross-reference
 
Titles with Series metadata (no resources are missing):
Series                                                       Desktop           Laptop
Bible Lessons Int                                             13                  17
Opening Up                                                       8                  32
 
I also note the following:-
- After uninstalling the Documents and Users folders were preserved whilst the Data folder was wiped
- I did not have to sign-in after installing; but
- My Collections were not restored (this old bug needs to be fixed)
I used the usual manual procedure to restore the Collections, but the logos4.log indicates it is only looking for metadata updates after 16 June 2011.
