-

i have written application in qt 5.4 (windows 7 ) , migrating windows 10 qt 5.5.. there changes in qt correct in code , code builds well, when comes run program there bunch of warnings . dont know , why comes from.

warnings :

shell\comdlg32\fileopensave.cpp(9456)\comdlg32.dll!00007fff0973260a: (caller: 00007fff0973a866) returnhr[prerelease](1) tid(b94) 80070490 element not found.     callcontext:[\pickermodalloop\initdialog\filedialoginitenterprisedata]  shell\ext\thumbnailcache\lib\thumbcacheapi.cpp(243)\thumbcache.dll!00007ffee54432dc: (caller: 00007ffee54434ff) returnhr[prerelease](1) tid(b94) 80004005 unspecified error shell\ext\thumbnailcache\lib\thumbcacheapi.cpp(153)\thumbcache.dll!00007ffee5438d28: (caller: 00007fff06713ea0) returnhr[prerelease](2) tid(b94) 80004005 unspecified error shell\ext\thumbnailcache\lib\thumbcacheapi.cpp(243)\thumbcache.dll!00007ffee54432dc: (caller: 00007ffee54434ff) returnhr[prerelease](3) tid(b94) 80004005 unspecified error shell\ext\thumbnailcache\lib\thumbcacheapi.cpp(243)\thumbcache.dll!00007ffee54432dc: (caller: 00007ffee54434ff) returnhr[prerelease](4) tid(b94) 80004005

the issue discussed here qt guys, , cannot it:

this unrelated qt; same happens when opening file in notepad. picker rt terminology; seems dialog implemented in terms of winrt file picker , goes awry there.
