Cannot find the file in the current directory when run elevated mode

[chkchun]

When we only put filename, and run silentCMD under elevated mode (run as administrator), it cannot find the file.

<setting name="DefaultBatchFilePath" serializeAs="String">
      <value>test.bat</value>
</setting>

I have to change the Environment.CurrentDirectory + filename
become Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + filename.
Then it only able to find the file for both normal mode & elevated mode.

This is a great program. Thanks.
