Link Planner 5.6.0 Unuseable after tech support

Called in with crash report for “Unexpected error” after installing/ upgrading to 5.6.0.
Tech Support “fix” removed the map now all I have is a white background with no terrain profiles.

Removing .dll files and changing the Environment parameters and updating windows files made this useless.
I have removed and reinstalled several times and cannot get back to 4.9.1 which was working.

This case was created for a crash issue on LINKPlanner version 5.6.0.

Resolution provided:
a few suggestions that we can try which may work around the problem:

Delete some Windows 10 specific DLLs

Open Explorer and navigate to the LINKPlanner installation directory (the default is C:\Program Files\Cambium Networks\LINKPlanner)

Delete MPR.dll and MSWSOCK.dll

Note that you will need administrator privileges on the computer to do this

Older versions of LINKPlanner removed these files, but this created compatibility issues for some users so we have started to leave them in on the Windows 10 build and this may be the cause of the current problem.

  1. Disable the online map.

Click Start → Run (Windows Key + R)

Enter “cmd” in the Open box and click OK

Type the following in the console:

setx LINK_PLANNER_HIDE_GMAP 1

setx LINK_PLANNER_SIMPLE_HTML 1

LINKPlanner will use a simple HTML viewer to render any HTML messages rather than the embedded Internet Explorer control, which is why the map disappears.

  1. Install the Microsoft C++ 2008 Redistributable Package

Visit https://www.microsoft.com/en-gb/download/details.aspx?id=11895, then download and install the package

LINKPlanner is using an older version of Python that uses this package. Usually, it is installed along with other applications, but it’s possible that users reporting the error do not have it installed.

As the issue is resolved, I will mark this case as closed.

Hi John,

4.9.1 should install in a completely separate location to 5.6.0. 4.9.1 is a 32-bit application so it installs to “C:\Program Files (x86)” by default and 5.6.0 is a 64-bit application so it installs in “C:\Program Files” by default. As a result you should be able to keep them both installed on your machine.

The only potential sticking point is some shared, generated files that get created in “%APPDATA%\LINKPlanner\modules”. Some users don’t have a problem, but you may find that things start to work if you delete the “modules” directory and then start LINKPlanner. Failing that, restart your machine and install again.

Lots of users are having issues with the map on 5.6.0, but we are unable to reproduce the problem, so for now the only solution is to disable the online map. If you do this, then you still have the offline map and the Google Earth import/export.

Thanks,

Andy
