8.8.5 is now publicly available: https://mega.nz/file/GKQx3aTB#1PY2AgBQh ... Sc5b2G1XhE
Here's the changelog:
Note: if you have used @technodevotee's restore_mssqllite script, installing 8.8.5 is not necessary: 8.8.5 actually restores more registry entries than the initial script I wrote (for completeness), but it shouldn't make any difference for WMC.The package was updated to automatically restore the Microsoft SQL CE components (sqlcecompact40, sqlceoledb40, sqlceqp40 and sqlcese40) that were removed by Microsoft in Windows 10 2004.
Thanks to everyone who offered to test it, it's muchly appreciated.
