Open Files In Desktop App By Default now license based and not functioning within Business Prem

dbrock 

I have two solutions.

1. Close Teams

1.2. WIN + R , %temp%\Microsoft , remove the folder "teams"
1.3. Start teams. 

If option still not there wrong version of Office is installed.

Solution number 2:
Go to config.office.com and create a XML config file that installs Proplus and removes all the other office installtions.

like this one:

<Configuration>
  <Remove>
    <Product ID="O365BusinessRetail" />
    <Product ID="O365ProPlusRetail" />
    <Product ID="O365BusinessEssentials" />
    <Product ID="O365BusinessPremium" />
    <Product ID="O365HomePremRetail">
      <Language ID="en-us" />
    </Product>
    <Product ID="O365HomePremRetail">
      <Language ID="da-dk" />
    </Product>
    <Product ID="O365HomePremRetail">
      <Language ID="fi-fi" />
    </Product>
    <Product ID="O365HomePremRetail">
      <Language ID="nb-no" />
    </Product>
    <Product ID="O365HomePremRetail">
      <Language ID="sv-se" />
    </Product>
    <Product ID="O365ProPlusRetail">
      <Language ID="fr-fr" />
    </Product>
    <Product ID="O365ProPlusRetail">
      <Language ID="nb-no" />
    </Product>
  </Remove>
  <Add OfficeClientEdition="64">
    <Product ID="O365ProPlusRetail">
      <Language ID="sv-se" />
    </Product>
  </Add>
</Configuration>

download an office setup file, start powershell with admin rights, paste:

*officesetupfilename*.exe /configure yourconfigfile.xml

restart pc after fidling with the office pakage or restart teams. 
Should do the trick.
