How to open XLL_ file?

The first thing you should do is just "doubleclick" on the XLL_ 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 Microsoft Excel

Programs to open XLL_ file

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

Step 2. Create association of Microsoft Excel with XLL_ files

However, it may happen that the application itself does not cause the XLL_ file to open in the Microsoft Excel application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties.

Using the "Change" button we can set the program to handle this type. 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.

Step 4. Check for the following problems with the XLL_ 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 XLL_ file may be unusually small compared to the original file. This is most often caused by a problem while downloading the XLL_ file. The only repair option is to download the file again.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file XLL_ or the program directory. As a result of the scan, sometimes it is not possible to recover XLL_ files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the XLL_ file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged XLL_ files. The easiest way to restore the file is from a backup or by contacting Microsoft Corporation, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted XLL_ 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. 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 XLL_ file to another location.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. 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 XLL_ file for a certain period of time. If this does not work either, restart the device.
