The patch.exe requires admin privileges on Windows 7. This is pretty annoying! The first thing that worked was just renaming the file to pach.exe Stupid windows. But I didn’t like that cause than I mostly typed it wrong and patch command was missing. I found a better solution:

Create a text file in the same directory with the name patch.exe.manifest

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
 <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
 <requestedExecutionLevel level="asInvoker"/>

Save as UTF8. Now it works. Well I have to test if it is possible to embedd the manifest than good bye $%&# asking for admin permission
