AXS files are not recognized by Windows 10

Problem description #

Association of .axs file extension is not saved for AxisVM.

However “Always use the program to open a file with this extension” is set for AxisVM files, Windows does not save it and asks the question next time when an AxisVM file is clicked.

Reason #

AxisVM installer uses the standard Windows method to associate the AXS file to AxisVM. Unfortunately, in lots of cases, the file extension association doesn’t work properly under Windows 10, not only for AxisVM.

A registration error can cause it because the user has no administrator rights during the setup process.

Solution #

Select Start menu, Settings > Apps > Default apps > Choose default apps by file type and try to set the association for .axs files to AxisVM, the association fails, it keeps displaying Choose a default...

However, if you right-click on the file and choose AxisVM checking Always use the program to open a file with this extension, the next time it opens .axs with AxisVM and Choose default apps by file type displays AxisVM as the default app.
