The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program.

Step 4. Check for the following problems with the PR4 file

Very often, the file may be size 0 or incomplete. This suggests truncating the PR4 file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the PR4 file that we want to open. Sometimes virus-infected PR4 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the PR4 files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular PR4 file corruption. You can restore the file from a backup or use Harvard Graphics help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file PR4 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the PR4 file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the PR4 file again. However, some background programs may block the PR4 file while scanning. If nothing helps, please reset the device.
