Installation v20 fails!

webbswebbs Global Mapper UserPosts: 8

Dear All,

Currently I am a user of GM 15, but I'm considering to do an upgrade to v20...

So I want to try it out with an installation of the test version.

The problem is that the installation with the installer does'nt work!

… the first steps are ok, but when it comes to the installation itsself it does not work:

the green bar runs from left to the right, but then turns back and starts new, … and so on …!

So the bar always runs from left to right, in an endless loop ….?

By now I have no idea what do do, can any body help?

Thank you,

    I suggest that you delete the installer you have, download a new one, and try again. If that does not work, please contact Blue Marble Support directly via email (
