Whenever I start DownloaderPro (1.7.1beta 2), automatically or manually, I get the error message that it was "unable to register the PolyImage Pro library", I shall start DP with Administrator rights.

Well, I do have Admin rights, always.

This problem is caused by some other app incorrectly registering PolyImagePro.dll. I am in the process of rewriting all of the code in DLPro and BBPro to use a different interface to PolyImagePro.dll to avoid this problem in future. This is going to take me several weeks and unfortunately will delay other developments but I can't continue to allow other apps to break DLPro and BBPro.
You can workaround the problem by identifying the other app and making sure it is using the latest version of PolyImagePro.dll (i.e. copy the newest version to its installation folder).

One program interfering - to those interested in a faster find - seems to be ArchiveCreator by Michael Tapes and Peter Morrone, which uses an older version of PolyImagePro.DLL.
