We hope we helped you solve the problem with the ADR file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the ADR file (apart from the lack of the proper application installed).

First - the ADR file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the ADR file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the ADR file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the ADR file has not been completed and it cannot be opened properly).
