What is VSTO file?

The VSTO file has been categorized as Misc Files. It was designed by Microsoft Corporation. In addition to this file, the Misc Files category includes 6033 related files. Microsoft Visual Studio 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.

How to open VSTO file?

An often recurring problem with Microsoft Visual Studio is that VSTO is not associated with the correct program file. Thus, when you open VSTO, the program selection wizard or some other program starts. How to solve such a problem?

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

An often overlooked issue is to make sure that Microsoft Visual Studio is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft Visual Studio 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 VSTO.

Programs to open VSTO file

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

Step 2. Create association of Microsoft Visual Studio with VSTO files

If the application is or has been freshly installed, but the VSTO file still does not use the Microsoft Visual Studio program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the 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. The "always use the selected program ..." field will set the Microsoft Visual Studio application as the default for handling the VSTO file.

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 Microsoft Visual Studio 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 VSTO file

If the above steps do not help, you can assume that the file itself is not correct. 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 VSTO file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our VSTO file. Sometimes virus-infected VSTO files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the VSTO file. 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 option of recovering data from damaged VSTO files. You can restore the file from a backup or use Microsoft Corporation help.
The program can also signal the fact of encryption. The encrypted VSTO 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move VSTO to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the VSTO file while scanning. If this does not work either, restart the device.
