How to open LOP file?

The most common problem when using MasterCook Layout Format is that a specific LOP is not associated with the program. Thus, when you open LOP, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the LOP 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 MasterCook

The first step is to check if the computer has the MasterCook program installed. The easiest method is to use the system search engine by entering the program name MasterCook in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open LOP files.

Programs to open LOP file

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

Step 2. Create association of MasterCook with LOP files

If, despite the installed application, the LOP file does not start in the MasterCook 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 displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the MasterCook application as the default for handling the LOP file.

Step 3. Update MasterCook to the latest version

If, despite the association of the MasterCook program with the MasterCook Layout Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the ValuSoft website or update the program from the application.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the LOP file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our LOP file. However, remember that not every infected LOP file can be recovered, so it is important to take care of regular backups.
Older version of LOP file may not always be supported by the latest software version. 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 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 LOP file corruption. The easiest way is to restore the file from a backup, if there is one, or contact ValuSoft
The program can also signal the fact of encryption. The encrypted LOP 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. These directories are write-protected to them and it's very hard to fix this problem. It is best to move LOP to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the LOP file again. However, some background programs may block the LOP file while scanning. If the problem persists, restart the machine.
