Didn't help. Also as mentioned above, I usually use the portable viewer which does not install. From what I can tell from Process Explorer, the program encounters some error condition and then silently exits (shuts itself down) without displaying anything on the screen and without logging an event. I am willing to get additional debug level detail so that you can get to the bottom of this issue because it might be affecting individuals that are downloading the program for the first time and writing it off when it does launch.
I have encountered the same issue with the viewer app on a single Windows 10 machine with version 188.8.131.52. I have tried the install and portable viewer options and both silently exit almost immediately after being launched (double-clicked on). Version 6.x works just fine. Version 184.108.40.206 does not log any errors in the Windows event log and Process Explorer shows the process existing. The same viewer program works on other Windows 10 machines that are the same build, so there is clearly an environmental variable at work. Any suggestions are welcome.
I have the same issue except with Windows Server 2012 R2 and Windows 10 machines. Neither shift key works. I have tried all the steps above and with multiple machines and the result is the same. I cannot log in because my password has uppercase and special characters.
