The SIS file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the SIS files. Below is a summary of the number of programs that support and open the SIS file on each system platform.
What is SIS file?
The file in the SIS format belongs to the Misc Files category. The author of this format is Symbian. Misc Files consists of 6033 similar files. Symbian Installation 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 main program that supports this format is Nokia Suite. This was created by Nokia Corporation. There are also 2 alternative programs to handle the SIS file. The UnSIS, Palm OS Emulator programs will also handle the file when the Nokia Suite program does not fulfill its role.
How to open SIS file?
The main problem with Symbian Installation Format is that the SIS file is incorrectly associated with programs. This causes the file SIS to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the SIS 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 Suite
In this case, you should first verify that the Nokia Suite application is installed on the computer. The easiest method is to use the system search engine by entering the program name Nokia Suite in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file SIS with Nokia Suite. Below is a list of programs that support the file SIS.
Programs to open SIS file
Remember to download programs supporting SIS files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Nokia Suite with SIS files
If, despite the installed application, the SIS file does not start in the Nokia Suite application, you must create a file association. 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 set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the SIS file with the Nokia Suite application.
Step 3. Update Nokia Suite to the latest version
If, however, after binding Nokia Suite with Symbian Installation Format 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 Nokia Corporation website and install the latest version.
Step 4. Check for the following problems with the SIS 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 SIS files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
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. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the SIS file that we want to open. However, remember that not every infected SIS file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the SIS 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 this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular SIS file corruption. The easiest way to restore the file is from a backup or by contacting Symbian, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file SIS 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 of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the SIS file to another location will fix the problem.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the SIS file for a certain period of time. If nothing helps, please reset the device.
