Trying to open/ launch Lightroom 5.7 and keep getting the error message "Lightroom encountered an error when reading from its preview cache and needs to quit. Lightroom will attempt to fix this problem the next time it launches".
LR5.7 will not open and just shuts down. Tried ver 5.6, but still the same. Deleted and re-installed LR but still the same. Anyone know how to fix this problem?
Delete the preview cache or, to be safe, move it to your desktop temporarily. It is a folder whose name is LR 5 Catalog Previews.lrdata and it is located alongside the catalog file whose default location is C:/....Pictures/Lightroom. Then launch LR and in the Library module go to Library/Previews/Build Standard Previews and LR will rebuild the cache.
