Visual Studio 2012 cannot not load extension

[thoemmi]

When opening a solution in Visual Studio 2012, I get an error message saying "The 'TidyTabsPackage' package did not load correctly."

In Visual Studio's log (%AppData%/Microsoft/VisualStudio/11.0/ActivityLog.xml) I see this entry:

<entry>
    <record>622</record>

</entry>

So I guess it's because TinyTabs references the Visual Studio 2013 version of Microsoft.VisualStudio.Shell.11, which is not installed on my machine.

Thanks for letting me know about this,

Will update and push a fix for this asap

Same for me.

@thoemmi @eltoncezar I am investigating this issue and working to fix.

I can install TidyTabs and run the extension in VS 2012 but the machine also has 2013 installed. I will need to setup a clean environment to test a fix.

Can you confirm that your environments do not have 2013 installed?

[eltoncezar]

Yes, I can confirm. No VS 2013 installed.

I came here to say that I have the exact same issue in the latest version of Tidy Tabs which at the time of this writing is 1.10.1. I am running Visual Studio 2012 and I don't have Visual Studio 2013 or higher installed. Was this never resolved?

My Visual Studio 2012 version:

Microsoft Visual Studio Professional 2012
Version 11.0.61219.00 Update 5
Microsoft .NET Framework
Version 4.6.00081

And the error from ActivityLog.xml:

CreateInstance failed for package [TidyTabsPackage]
{324CAC6D-FF67-4E2E-8FC9-7A587B2D6045}
80070002

I wanted to give it another try and I was amazed to see that this issue was still open...
