What is PWO file?

The PWO file has been categorized as Misc Files. The creator of this file is Certara. Misc Files consists of 6033 similar files. WinNonlin Output is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. The main program that supports this format is WinNonlin. This was created by Certara.

How to open PWO file?

The main problem with WinNonlin Output is that the PWO file is incorrectly associated with programs. This causes the file PWO to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the PWO 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 WinNonlin

An often overlooked issue is to make sure that WinNonlin is installed on the computer. This can be achieved by typing WinNonlin into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open PWO files.

Programs to open PWO file

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

Step 2. Create association of WinNonlin with PWO files

If, despite the installed application, the PWO file does not start in the WinNonlin application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. 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. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the WinNonlin application as the default for handling the PWO file.

Step 3. Update WinNonlin to the latest version

If, despite the association of the WinNonlin program with the WinNonlin Output file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Certara website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to PWO files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the PWO file that we want to open. Sometimes virus-infected PWO 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 PWO files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair PWO file corruption. The easiest way to restore the file is from a backup or by contacting Certara, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted PWO files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the PWO file to another location.
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. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the PWO file for a certain period of time. If nothing helps, please reset the device.
