To edit ACTPROJ file, we strongly recommend installing software that works with ACTPROJ files. Of course, there are probably ACTPROJ Online Editors available, but none of them will be able to provide such a wide range of available options as dedicated software.
The installation of the program that supports the ACTPROJ file does not guarantee that the file can be edited. Additional information about the ACTPROJ file extension can be found here.
This is definitely the surest way. Use any of the programs that support the ACTPROJ file to check if it allows you to edit the file. It's safest to download the software from the developer's website. Links to the websites of software producers can be found on the software subpages. Below you will find some examples of software programs that support the ACTPROJ file (so it is very possible that they can edit files in ACTPROJ format).

By far the safest way is to use file editing programs that works with the ACTPROJ extension.
