Remember to download programs supporting CT1 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Systems Management Server (SMS) with CT1 files

However, it may happen that the application itself does not cause the CT1 file to open in the Microsoft Systems Management Server (SMS) 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.

If, however, after binding Microsoft Systems Management Server (SMS) with SMS Proposed Site Control there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the CT1 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. This suggests truncating the CT1 file contents when downloading or copying. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file CT1 or the program directory. However, remember that not every infected CT1 file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the CT1 file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular CT1 file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted CT1 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. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the CT1 file to another location.
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. Some anti-virus or backup software may occupy the CT1 file for a certain period of time. If the problem persists, restart the machine.
