plugins.json - Manual (Fixed or By Weight and By Total) Problem

I have upgraded from 3.9 to 4.2. I did have a lot problems with my application, having error like
"The application could not start".

i Have made a copy of the old installedplugins.txt and renamed it to plugins.json an
uploaded it to app_Data folder.

My application always crashes and will not start when i doo this.

If i keep the new plugins.json and do not replace it with the old installedplugins.txt,
then my application will run and i can use the website.

But now the problem is that if i try to install "Manual (Fixed or By Weight and By Total)"
nothing happens and "Manual (Fixed or By Weight and By Total)" is not installed.

My plugins.json then looks like this
{
  "InstalledPluginNames": [
    "SevenSpikes.Core",
    "SevenSpikes.Nop.Plugins.HtmlWidgets",
    "SevenSpikes.Theme.Uptown",
    "Payments.QuickPayV10"
  ],
  "PluginNamesToUninstall": [],
  "PluginNamesToDelete": [],
  "PluginNamesToInstall": [
    {
      "Item1": "Shipping.FixedByWeightByTotal",
      "Item2": "7f2b7952-0ee0-4b2b-8387-950cc2792b88"
    }
  ]
}

If i try to move  "Shipping.FixedByWeightByTotal" to the "InstalledPluginNames" section,
Then the website crashes again and will not start.

Somehow "Shipping.FixedByWeightByTotal"  must be the problem, but what to do about it ?

Now i see in my log file

So the problem is in the database:

The table required for the Shipping.FixedByWeightByTotal plugin is already added to the database.
You can manually delete the table using ssms if it does not have any record and reinstall the plugin.
Or you could add
Shipping.FixedByWeightByTotal in the plugins.json file in the InstalledPluginNames which will denote that the plugin is installed in the system.

Just paste below at your plugins.json

{
  "InstalledPluginNames": [
    "SevenSpikes.Core",
    "SevenSpikes.Nop.Plugins.HtmlWidgets",
    "SevenSpikes.Theme.Uptown",
    "Shipping.FixedByWeightByTotal",
    "Payments.QuickPayV10"
  ],
  "PluginNamesToUninstall": [],
  "PluginNamesToDelete": [],
  "PluginNamesToInstall": []
}

Thanks - this one works perfect
