The main problem with IMovie Theater Library is that the THEATER file is incorrectly associated with programs. This causes the file THEATER to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

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

Programs to open THEATER file

Step 2. Create association of iMovie with THEATER files

If the application is or has been freshly installed, but the THEATER file still does not use the iMovie program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. 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. Checking the "Always use the selected program ..." box will permanently associate the THEATER file with the iMovie program.

Step 3. Update iMovie to the latest version

If, however, after binding iMovie with IMovie Theater Library there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Apple, Inc. page and install.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The THEATER file may be unusually small compared to the original file. Usually this applies to THEATER files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the THEATER file that we want to open. Sometimes virus-infected THEATER files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the THEATER file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular THEATER file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Apple, Inc.
When reading, a message appears that the file was encrypted or corrupted. The encrypted THEATER 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the THEATER file to another location will fix the problem.
This problem usually affects more complex files. In this case, the THEATER file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the THEATER file while scanning. If nothing helps, please reset the device.
