Installing the programme
If you are planning to install the programme on a machine running Windows NT/2000/XP/Vista/Win7, you must have administrative rights to do this. The programme can not be installed on earlier versions of Windows.
You may use the defaults offered by the installation programme if you wish, but you may place it anywhere on your system. If more than one person is to be able to use the programme, make sure to check the little box:
The programme and help files will be copied to a directory of your choice. Thomas Niemann's file PTLens.dat in the version current at the time when the installation programme was set up will also be installed. It is strongly recommended that you update these files following the instructions given here..
Just before the installation terminates and the final installation screen appears, you are given the opportunity to set the permissions on the installation directory and its subdirectory so that non-administrative users may update the profiles themselves. Non-administrative users must have the right to modify these files. There is a little check box which causes the installation programme to spawn a system programme called xcacls.exe when it closes, and this in turn sets permissions on the directories and files appropriately. If unchecked, you as administrator, must set the permissions manually. If for some reason, xcacls.exe can not perform the required function, the installation programme may hang. In that case, you can safely terminate it using the Task Manager, but you will have to set the permissions by hand.
These operations can be done using the Windows Explorer.
To set, view, change, or remove special permissions for files and folders open the Windows Explorer, and then locate the file or folder for which you want to set special permissions. Right-click the file or folder, click Properties, and then click the Security tab if it is visible.
To display the Security tab if it is not visible:
Open Folder Options in Control Panel.
Click Start, and then click Control Panel.
Click Appearance and Themes, and then click Folder Options.
On the View tab, under Advanced settings, clear the check box "Use simple file sharing".
Turn on read/write/modify/execute access rights on the AirPhoto directory and its sub-directories setup (enable viewing hidden files), plugins, csvdata. Deny all other rights.
Administrators should check this with XCALC.EXE in command line mode. If all is well you should see something like:
