Problems installing Defending the Reich on Vista

Try going into Explorer and right clicking on the DTR folder. Click Properties and uncheck the Read Only box under attributes under the General Tab. Then click on the Security Tab and click Edit under Group or User Names. Select Users and then below that select Full Control ->Allow and then click Apply. This will change the permissions of your folder in under the Program Files folder. Then install the files and see if that won't work. You could also try creating a folder, call it HPS, outside the Program Files folder and then install the game there and see if you can install the three patch files.
