Unofficial Patch for 7.62

[Slice]

Hi guys, as someone else posted in here, on Windows 7 64 clean install of 7.62 and then unzipping and manually copying the unofficial patch files into the 7.62 folder (overwriting where necessary fine), but when I go to run the patch (even with the msvcr71.dll in or not) I get a long list of ;

The directory is not empty.

<. and so on lots more..then..>

Doesn't matter if run as admin or not.

If I run again obviously some files have been self deleted so get the obvious;

"'azp.exe' is not recognized as an internal or external command,
operable program or batch file.
The system cannot find the file directory.a.
Could Not Find D:\Games7\7.62 - High Calibre\directory.a
Could Not Find D:\Games7\7.62 - High Calibre\files.a
Could Not Find D:\Games7\7.62 - High Calibre\azp.exe

So I unpack it again to try again etc.

Any ideas?
Do I need to play the game some first? Or not setup a config or ?
(also if I unzip directlty in there same issue). I may be doing something stupid but I'm an experienced PC user.

Thanks!
