Troubleshooting
Visual Studio Start up Errors
package did not load correctly
To resolve the problem, close all Visual Studio instances, then delete all files in the following folder:
Visual Studio 2013
%localappdata%\Microsoft\VisualStudio\12.0\ComponentModelCache
It worked fine for me. Thanks tothis article.
Visual Studio 2015
%localappdata%\Microsoft\VisualStudio\14.0\ComponentModelCache
Visual Studio 2017
%localappdata%\Microsoft\VisualStudio\15.0_xxxx\ComponentModelCache
Visual Studio Shell 2010 invalid license data
Use regedit go to HKEY_CLASSES_ROOT and look for Visual Studio.DTE
Since i have Visual Studio 2015 installed i have 3 DTE, one is VisualStudio.DTE, the other Visual StudioDTE.10.0 and VisualStudio.DTE.14.0
Go to VisualStudio.DTE.14.0 ( or whatever version of Visual studio you have installed) and click CLSID. Copy the Default (Double click Default and Copy the key inside), now go back to Visua Studio.DTE and double click the Default there and paste the key you just copied.
On VisualStudio.DTE go to CurVer and double click the key there to Edit it. Change the 10.0 in the end to 12.0 or 13.0 or 14.0, depending on what version of Visual Studio you have and you are done
Project Loading Error
The project type is not supported by this installation
Every Visual Studio project has a project type (Windows project, Smart Device project, Web Site project, etc.) and in some cases more than one type (subtypes or flavors).
Every project type is identified by a unique Guid, so every project has one or more project type Guids.
Project type Guids are stored generally in the project file:
<PropertyGroup>
<ProjectTypeGuids>{A860303F-1F3F-4691-B57E-529FC101A107};{F184B08F-C81C-45F6-A57F-5ABD9991F28F}</ProjectTypeGuids>
...
</PropertyGroup>
But for some special projects (such as some database projects) and projects lacking a file (such as Web Site projects), the project type is stored also in the solution file:
Microsoft Visual Studio Solution File, Format Version 10.00
# Visual Studio 2008
Project("{F184B08F-C81C-45F6-A57F-5ABD9991F28F}") = "SqlServerProject1", "SqlServerProject1.vbproj", "{BE5F0BE0-93CD-4FCE-A853-9096A442DF1B}"
EndProject
