How to open SISX file?

The most common problem when using Symbian OS Installation Format is that a specific SISX is not associated with the program. This is manifested by the fact that SISX files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the SISX 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 Nokia PC Suite

In this case, you should first verify that the Nokia PC Suite application is installed on the computer. The easiest method is to use the system search engine by entering the program name Nokia PC Suite in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support SISX files.

Programs to open SISX file

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

Step 2. Create association of Nokia PC Suite with SISX files

However, it may happen that the application itself does not cause the SISX file to open in the Nokia PC Suite application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting 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 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 Nokia PC Suite application as the default for handling the SISX file.

Step 3. Update Nokia PC Suite to the latest version

The fault may also lie with the Nokia PC Suite program, it is possible that Symbian OS Installation Format requires a newer version of the program.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. Usually this applies to SISX files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file SISX or the program directory. As a result of the scan, sometimes it is not possible to recover SISX files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the SISX 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 the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular SISX file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted SISX 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. The problem is only writing to the file, not reading it. If possible, you can try to move the SISX 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. Sometimes it is necessary to wait a while before referencing the SISX file again. 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.
