UMS won't start in Windows 10 [Solved]
Posted: Mon Jun 22, 2020 2:51 am
Hi. I've googled this issue and searched the forums, however none of the solutions seem to be working for me. I have a 3-week old Windows 10 64-bit machine, where I initially installed UMS 9.5.0 and it was working fine at first. Then one day it wouldn't launch at all. When clicking on UMS shortcut on desktop nothing happens. No javaw.exe can be seen running in task manager, nothing. I've tried re-installing different versions (tried 8.2.0, 9.5.0 and now 9.6.2), making sure I've deleted all traces of previous install before reinstalling (install folder from Program Files (x86) and UMS folder from ProgramData); with the same result every time. I've never ran UMS as a windows service, so I don't think that's an issue.
Things I've tried so far:
-install JRE (Version 8 Update 251) before (and after) installing UMS - no difference. Tried both 32- and 64-bit
-install UMS without JRE
-running UMS as administrator
-launching UMS.exe from command prompt - no error message of any kind, just nothing happens
-launching UMS.bat from command prompt - without JRE I get an error message "Windows cannot find 'javaw'. Make sure you typed the name correctly, and then try again."; with JRE installed I get no error message, but nothing happens
-changing path to javaw.exe within the .bat file (pointing to /jre14-x64/bin/) and running it - no error message and nothing happens
-changing java heap size to 128MB instead of default 1280 in the installer, both with- and without "clean install" options checked
Since the program doesn't launch at all I can't make UMS create any trace logs. I did include the debug.log, which says the same things in every scenario. I'm thinking I might have inadvertently turned off some windows service which UMS might require to run, but haven't found anything related to it. Any help would be appreciated.
