This may interfere with your operating system link your SIS file to the correct application software, influencing the so-called "file extension associations".

Sometimes simple reinstalling Steam may solve your problem by linking SIS to Steam correctly. In other cases, problems with file associations may result from bad software programming developer and you may need to contact the developer for further assistance.

. Since your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking on it. Try updating Steam to the latest version to ensure you have the latest patches and updates.

This may seem too obvious, but often The SIS file itself may be causing the problem. If you received a file via an email attachment or downloaded it from a website and the download process was interrupted (such as a power outage or other reason), the file may become damaged. If possible, try getting a new copy of the SIS file and try opening it again.

This process can be made easier by using driver update software such as DriverDoc.

If the steps do not solve the problem and you are still having problems opening SIS files, this could be due to lack of available system resources. Some versions of SIS files may require a significant amount of resources (e.g. memory/RAM, processing power) to properly open on your computer. This problem is quite common if you are using fairly old computer hardware and at the same time a much newer operating system.

This problem can occur when the computer is having difficulty keeping up with a task because the operating system (and other services running in the background) may consume too many resources to open the SIS file. Try closing all applications on your PC before opening the Steam Game Backup Information File. By freeing up all available resources on your computer you will provide the best conditions for attempting to open the SIS file.

If you completed all the steps described above and your SIS file still won't open, you may need to run equipment update. In most cases, even when using older versions of hardware, the processing power can still be more than sufficient for most user applications (unless you're doing a lot of CPU-intensive work, such as 3D rendering, financial/scientific modeling, or intensive multimedia work) . Thus, it is likely that your computer does not have enough memory(commonly called "RAM" or random access memory) to perform the task of opening a file.

Try refreshing your memory to see if this will help you open the SIS file. Today, memory upgrades are quite affordable and very easy to install, even for the average computer user. As a bonus, you you'll probably see a nice performance boost while your computer performs other tasks.

Summary: Either way, most problems that occur when opening SIS files are due to not having the correct application software installed on your computer.
