    I have installed axcrypt on windows 10 but have an unhandled exception “the path is not of a legal form” I don’t know what this means nor how to proceed. I have tried uninstalling and re-installing but get the same error.

    Hi Svante

    thanks for your rapid reply.

    I have just booted up my laptop to get a screen dump and the fault has mysteriously disappeared and axcrypt appears to be working fine.

    Your mystical powers are working well!

    Problem solved then David!

    The message you spoke about is a generic C# error but as long as it’s gone away then there is no problem.

    Microsoft have today released a number of critical security patches and general updates, one of which is the Microsoft .NET Framework 4.7. It may have been that you failed to restart after installing/updating to the latest version of AxCrypt and the .NET service had been terminated by the Windows Server Update Services.
