My app uses ClickOnce tehcnology. Today I needed to run it as administrator. I modified the manifest file from
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
to
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
However VS cannot compile the project:
Error 35 ClickOnce does not support the request execution level 'requireAdministrator'.
I think it's impossible to use them at once. Isn't it? I need to change the system time, can I do that in application level? Can I emulate it, so app. can do what I want. I change time +2 hours then put back for a second. I got a few dlls and they ask for time.
Time is a system-wide thing, you can't change it just for your process. The only way to lie about it to your dependencies is to hook the API, using Detours or something similar. Not allowed if you're a lowly user account.
Modifying the time requires the "Change the system time" and/or "Change the time zone" privileges (which the Administrator account is normally given).
And as mentioned by @Chris, admin and ClickOnce aren't compatible.
