CADViewer Redline Markup Format is supported by 3 operating systems. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others.

How to open RED file?

The main problem with CADViewer Redline Markup Format is that the RED file is incorrectly associated with programs. This is manifested by the fact that RED files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the RED 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 CADViewer

The first step is to check if the computer has the CADViewer program installed. This can be achieved by typing CADViewer into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file RED.

Programs to open RED file

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

Step 2. Create association of CADViewer with RED files

If the application is or has been freshly installed, but the RED file still does not use the CADViewer 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 select the desired program. 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. Checking the "Always use the selected program ..." box will permanently associate the RED file with the CADViewer program.

Step 3. Update CADViewer to the latest version

If, despite the association of the CADViewer program with the CADViewer Redline Markup 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 Tailor Made Software website or update the program from the application.

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

Of course, it may happen that despite the above steps, the file still does not work. 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 RED file. The file should be downloaded again, making sure that the process has finished correctly.
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. However, it is important to scan the entire system, not only the file RED or the program directory. Sometimes virus-infected RED files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the RED 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 this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular RED file corruption. The easiest way to restore the file is from a backup or by contacting Tailor Made Software, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted RED 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 RED to a different directory.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the RED file again. However, some background programs may block the RED file while scanning. If nothing helps, please reset the device.
