How to open MPPX file?

The most common problem when using Microsoft Project Project is that a specific MPPX is not associated with the program. This causes the file MPPX to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the MPPX file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Project

The first step is to check if the computer has the Microsoft Project program installed. To do this, enter the name Microsoft Project into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support MPPX files.

Programs to open MPPX file

Remember to download programs supporting MPPX files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Project with MPPX files

If the application is or has been freshly installed, but the MPPX file still does not use the Microsoft Project program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the Microsoft Project application as the default for handling the MPPX file.

Step 3. Update Microsoft Project to the latest version

The fault may also lie with the Microsoft Project program, it is possible that Microsoft Project Project requires a newer version of the program. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the MPPX 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. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file MPPX or the program directory. However, remember that not every infected MPPX file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the MPPX file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular MPPX file corruption. You can restore the file from a backup or use Microsoft Corporation help.
The program indicates that the file is encrypted or corrupted. The encrypted file MPPX 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the MPPX file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the MPPX file while scanning. If the problem persists, restart the machine.
