How to open API file?

An often recurring problem with Acrobat Plug-in is that API is not associated with the correct program file. Thus, when you open API, 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 API 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 Adobe Acrobat

The first step is to check if the computer has the Adobe Acrobat program installed. The easiest method is to use the system search engine by entering the program name Adobe Acrobat in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file API.

Programs to open API file

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

Step 2. Create association of Adobe Acrobat with API files

However, it may happen that the application itself does not cause the API file to open in the Adobe Acrobat application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. 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 Adobe Acrobat application as the default for handling the API file.

Step 3. Update Adobe Acrobat to the latest version

If, however, after binding Adobe Acrobat with Acrobat Plug-in there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Adobe Systems Incorporated website and install the latest version.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the API file contents when downloading or copying. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the API file that we want to open. Sometimes virus-infected API files cannot be recovered, so make a backup in advance.
Older version of API file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair API file corruption. You can restore the file from a backup or use Adobe Systems help.
The program can also signal the fact of encryption. The encrypted API files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
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 API file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file API to close. However, some background programs may block the API file while scanning. If this does not work either, restart the device.
