Re: [Wrapper-user] Running wrapper in console mode with elevated priviledges

[Christian M. <chr...@ta...>]

Hello Alex,

from what it seems, does you JNI function com_wm_distman_helpers_Registr
Helper_setExpandStringValueNative cause a crash.
When you run the application as Administrator, does it succeed?
In any way, there should be some error handling if it does not run as
administrator.

Since version 3.5.7 of the Wrapper, when running on Windows Vista/7/8/etc.,
where UAC is active, the Wrapper is actually able to request elevation and
run elevated, whenever it detects it doesn't run elevated and is going to
interact with a Windows Service.
When it requests elevation can however not being configured by the user. So
for instance when running as Console application, the Wrapper won't request
elevation, since for the Wrapper process it is not mandatory.

If you want to make sure the Wrapper runs always elevated, for now I'd
suggest to take a look at this:
http://www.howtogeek.com/howto/windows-vista/always-start-an-application-in-administrator-mode-on-windows-vista/

I will take also a look to add a conf-property to the Wrapper, to tell the
Wrapper to always request elevation.

Hope this information helps you out.

Cheers,

Christian
