How to open TLH file?
An often recurring problem with Typelib Generated C/C++ Header Format is that TLH is not associated with the correct program file. Thus, when you open TLH, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the TLH 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 Visual Studio
The first step is to check if the computer has the Microsoft Visual Studio program installed. To do this, enter the name Microsoft Visual Studio into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file TLH with Microsoft Visual Studio. Later in this article you will find a list of programs that can open TLH files.
Programs to open TLH file
Remember to download programs supporting TLH files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Microsoft Visual Studio with TLH files
If the application is or has been freshly installed, but the TLH file still does not use the Microsoft Visual Studio program, it means no association. It is most convenient to call the context menu with the right mouse button and select 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the TLH file with the Microsoft Visual Studio application.
Step 3. Update Microsoft Visual Studio to the latest version
If, despite the association of the Microsoft Visual Studio program with the Typelib Generated C/C++ Header Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.
Step 4. Check for the following problems with the TLH 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:
The TLH file may be unusually small compared to the original file. This is most often caused by a problem while downloading the TLH file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our TLH file. However, remember that not every infected TLH file can be recovered, so it is important to take care of regular backups.
Older version of TLH file may not always be supported by the latest software version. 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 the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair TLH file corruption. You can restore the file from a backup or use Microsoft help.
The program can also signal the fact of encryption. The encrypted TLH 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. Copying the TLH file to another location will fix the problem.
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 you have to wait for the session to the file TLH to close. However, some background programs may block the TLH file while scanning. If the problem persists, restart the machine.
