How to open PL3 file?
The most common problem when using Harvard Chart Palette is that a specific PL3 is not associated with the program. Thus, when you open PL3, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the PL3 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 Harvard Graphics ChartXL
An often overlooked issue is to make sure that Harvard Graphics ChartXL is installed on the computer. To do this, enter the name Harvard Graphics ChartXL into the 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 PL3 files.
Programs to open PL3 file
Remember to download programs supporting PL3 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Harvard Graphics ChartXL with PL3 files
If the application is or has been freshly installed, but the PL3 file still does not use the Harvard Graphics ChartXL 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. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the PL3 file with the Harvard Graphics ChartXL program.
Step 3. Update Harvard Graphics ChartXL to the latest version
The fault may also lie with the Harvard Graphics ChartXL program, it is possible that Harvard Chart Palette requires a newer version of the program. This can be done using the application (if it provides such options) or from the Harvard Graphics website and install the latest version.
Step 4. Check for the following problems with the PL3 file
The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. Usually this applies to PL3 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 computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file PL3 or the program directory. As a result of the scan, sometimes it is not possible to recover PL3 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of PL3 file may not always be supported by the latest software version. 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 this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular PL3 file corruption. The easiest way to restore the file is from a backup or by contacting Harvard Graphics, 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 file PL3 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. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the PL3 file to another location.
This problem only occurs with more complex files. In this case, the PL3 file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file PL3 to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
