      Lightroom 6.5.1 crashes and restarts every 3 minutes; faulting module: mfc120u.dll.


      OS is Windows 10 Pro 64-bit. Below is the problem report:

      During the crash the application disappears and restarts.

      Yesterday Lightroom crashed every 3 minutes, with a total number of crashes of 18 in 1 hour.


      What's going on? Can the dll be replaced by a newer/older version to prevent this from happening?
