Qt version: 5.10
Windows 10 professional
Build env: mingw 64 bit env.
QTIFW generated installer fails to create maintenance tool under circumstance:
- A user who has Administrator rights has invoked installer.
- The destination folder is C:\Program Files\Program_name

QTemporaryFile cannot copy,rename files even if it is in "elevated process".
(I successfully fixed this problem by changing the code to delegate copy/rename task to QFile instead of using QTemporaryFile)
- is replaced by
