Windows – opening a file with admin priviliges in windows

I was getting the very same error and I managed to sort it out. Though in my case, even though the same error occurred on every start of the machine, the service was running, as I was able to use my app. But I seriously wanted to get rid of this problem so the client will not be forced to see this annoying error.

The way I did it was set up the tomcat7w.exe to always start as an administrator. Exactly you do it in the following way: right click on the tomcat7w.exe which is in the 'bin' folder of the tomcat installation, select 'Properties', then in 'Compatibility' tab under 'Privilege Level' select the 'Run this program as an administrator'.

I have put my answer for completeness as I think this might be the only way for Win 7 Home users, as in this version there is simply no option to set Local Policies which is required in the answer provided by @ta.speot.is (BTW +1)

Turning off the UAC prompt for specific programs, or adding a program to a UAC “whitelist” have been common questions since Vista was released.

As you can see, there are lots of questions about it (many of them right here at SU). Unfortunately there is no practical solution to this because there is no “whitelist” (yet? still?)

Instead, you can use a non-ideal, convoluted method using the Task Scheduler to bypass the UAC prompt for specific programs by creating a task, setting it to use admin privileges, and entering the username and password.

Otherwise, you have to either turn down/off the UAC setting or live with it. At least setting the program to always use Admin privileges via the shortcut or compatibility tab like the two suggestions given here helps a little.
