What is OCA file?
The OCA file has been categorized as Developer Files. The author of this format is Microsoft. Developer Files consists of 1205 similar files. Custom Control Library Type Format is most often found on 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The Microsoft Visual Studio application is recommended to open the file. It was released by Microsoft Corporation. There are also 1 alternative programs to handle the OCA file. Microsoft Visual Basic will apply when it is not possible to use Microsoft Visual Studio.
How to open OCA file?
The main problem with Custom Control Library Type Format is that the OCA file is incorrectly associated with programs. This is manifested by the fact that OCA files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the OCA 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 Visual Studio
The first step is to check if the computer has the Microsoft Visual Studio program installed. This can be achieved by typing Microsoft Visual Studio into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file OCA.
Programs to open OCA file
Remember to download programs supporting OCA files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Microsoft Visual Studio with OCA files
If, despite the installed application, the OCA file does not start in the Microsoft Visual Studio 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. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the OCA file with the Microsoft Visual Studio application.
Step 3. Update Microsoft Visual Studio to the latest version
The fault may also lie with the Microsoft Visual Studio program, it is possible that Custom Control Library Type Format 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 OCA file
Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. Usually this applies to OCA 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 most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our OCA file. Sometimes virus-infected OCA 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 OCA files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged OCA files. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
The program indicates that the file is encrypted or corrupted. The encrypted file OCA 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move OCA to a different directory.
This problem only occurs with 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. If the error persists after closing other programs, wait for a while. 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.
