How to open GM81 file?

The main problem with Game Maker 8.1 Project Format is that the GM81 file is incorrectly associated with programs. This is manifested by the fact that GM81 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 GM81 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 GameMaker

In this case, you should first verify that the GameMaker application is installed on the computer. The easiest method is to use the system search engine by entering the program name GameMaker in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file GM81 with GameMaker. Later in this article you will find a list of programs that can open GM81 files.

Programs to open GM81 file

Remember to download programs supporting GM81 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of GameMaker with GM81 files

If the application is or has been freshly installed, but the GM81 file still does not use the GameMaker program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. 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 GameMaker application as the default for handling the GM81 file.

Step 3. Update GameMaker to the latest version

If, despite the association of the GameMaker program with the Game Maker 8.1 Project Format file, the file still does not open, check the program version and possibly update it to the newest version.

Step 4. Check for the following problems with the GM81 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. This is most often caused by a problem while downloading the GM81 file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the GM81 file that we want to open. Sometimes virus-infected GM81 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the GM81 files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair GM81 file corruption.
The program can also signal the fact of encryption. The encrypted GM81 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move GM81 to a different directory.
This problem only occurs with more complex files. In this case, the GM81 file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the GM81 file again. Some anti-virus or backup software may occupy the GM81 file for a certain period of time. If the problem persists, restart the machine.
