    Can anyobody help with "Assertion failed" errpor after Windows 10 upgrade


      Hi all,


      I used to successfully run Lightroom 5.7 on Windows 8 until recently I upgraded to Windows 10. Since then, I get an 'assertion failed' error and Lightroom does not open. I looked this error up and seems to have been a common theme for LR 5.4 in the days. So I tried all suggested fixes, but even registry checks and re-installing did not help. I cannot get it to work. Now: What can I do? Any idea?
