Hello,

I just added a new repo to Travis and re-used my .travis.yml from another C# project and just updated the .sln filename. But the new repo build always fails due to `AxImp.exe`missing or being in two locations. I’m not familiar enough with the process to debug this:

```
/usr/lib/mono/msbuild/Current/bin/Microsoft.Common.CurrentVersion.targets(2721,5): warning MSB3084: Task attempted to find "AxImp.exe" in two locations. 1) Under the "/usr/lib/mono/4.5/" processor specific directory which is generated based on SdkToolsPath 2) The x86 specific directory under "/usr/lib/mono/4.5/" which is specified by the SDKToolsPath property. You may be able to solve the problem by doing one of the following: 1) Set the "SDKToolsPath" property to the location of the Microsoft Windows SDK. [/home/travis/build/tryallthethings/Discord-Disco/DiscordDisco/DiscordDisco.csproj]

1283/usr/lib/mono/msbuild/Current/bin/Microsoft.Common.CurrentVersion.targets(2721,5): error MSB3086: Task could not find "AxImp.exe" using the SdkToolsPath "/usr/lib/mono/4.5/" or the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\NETFXSDK\4.8\WinSDK-NetFx40Tools-x86". Make sure the SdkToolsPath is set and the tool exists in the correct processor specific location under the SdkToolsPath and that the Microsoft Windows SDK is installed [/home/travis/build/tryallthethings/Discord-Disco/DiscordDisco/DiscordDisco.csproj]

```

Could you please have a look?

I’m not using any ActiveX-Control in my project and I couldn’t find any ActiveX reference in the additional library I added.

Thank you! That COMReference was an not used Reference to the Windows Media Player library. Removing it fixed the issue.
