Rig Manager will not install new or any older version now.

    Tried to install the newest version and it stopped in the middle of the installation.

    The installation failed partway through.

    Windows rolled back the installation and now I don't have RM installed anymore.

    Tried earlier versions and they failed also.

    I had that with a previous RM update some months ago.

    After some headscratching I found this to be a problem of the installer not being able to overwrite existing data in the RM directory. I manually deleted what was in there (the Rig database is in a different directory in Windows, so that was not a problem, but I did a backup anyway).

    After that the install went smoothly and I could also rollback to an older version as well.

    What actually created that hickup I never found out. Could be something with the Windows file access that got corrupted.
