I have built a simple Qt service. It works fine on Windows XP but fails on Windows 7 x64 and Windows Server 2008 R2 x64. (I guess it should fail with any Windows version >= 6.0.)

The system cannot find the path specified. C:/Windows/system32/ssl/client-key.pem

Of course, this file exists. I am opening it in "read only" mode.

Does anyone have any idea ?

Many thanks in advance.
