RP9 File Extension

How to open RP9 file?

After double-clicking on the unknown file icon, the system should open it in the default software that supports it. If this does not happen, download and install the E-UAE software and then manually associate the file with it.

Step 1. Download and install E-UAE

If there is no E-UAE or similar software in the system that supports files with the RP9 extension, you must first download and install it. Below you will find a list of the most-used applications that work with RP9. After going to the subpage of the program you will find a link to the developer's website, where you can safely download the software installer.

Step 2. Associate E-UAE with the RP9 file extension

If the user already has one of the applications installed, the next step will be to associate it with the file extension RP9. This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. The second way is simpler and definitely recommended for less advanced users.

• Right click on the unknown RP9 file you want to open
• Select "Open with" from the menu
• Click "Choose another application"
• Click "More applications"
• Click "Find more applications on this PC" and indicate the installation location of the appropriate program
• Finally, select the "Always use the selected program to open RP9 files" option and confirm the whole operation.

Remember! Manually editing the system registry is only recommended for advanced users, and changes made to it without proper knowledge may result in damage to the system.

Step 3. Check out other possible problems related to RP9 files.

Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the RP9 files. You should then find out what is the reason of the problem.

• Check if the RP9 file is not infected - When the file RP9 is infected with a virus or malware, it probably will not be able to be opened correctly. In this case, scan the RP9 file and take the actions recommended by the antivirus program installed on the system. Most often it is disinfection or deletion of an infected file.
• Check if you, as the operating system user, have appropriate permissions to work with the file RP9
• Check if the icon is an element of the correct file but not only a shortcut to the location where the RP9 file no longer exists.
• Check that the system has the necessary resources to run the E-UAE application and open the RP9 file.
• Check if the file is complete - Sometimes it happens that the RP9 file was not copied completely from the external Flash memory, or downloaded from the Internet. When the file is incomplete, it is not possible to open it correctly. In this case, please download or copy the file RP9 again.

Step 4. Contact an IT expert

When all of the above methods have failed, it remains to contact an IT specialist or developers of the E-UAE program.
