There is no information about error code 1526 in the Printing Management System application. However, you will need to fix this problem using a manual way. The first thing to do is to make sure the application isn't corrupted. Re-install the product using its installer or CD then repeat the step in the application. Secondly, check your username (if you use one) to make sure that you have permission to do so. Alternatively, run the application as Administrator, because if you are trying to write to a protected area of the disk (system partition) without Administrator access, then errors will appear.
