PPM Tricks

If you have the below error in Visual Studio when you try and debug a SharePoint App: Severity Code Description Project File Line Error Error occurred in deployment step 'Install app for SharePoint': The file exists. (Exception from HRESULT: 0x80070050) [AppName]  0 You have properly already tried:  - Clean the solution  - Manually uninstall the solution  - Upgraded the App version number  - Retracting the solution If none of the above works and you are pulling your hair for a solution, try and run Visual Studio in Administrative mode . This have fixed the problem for me many times and i think it was time to share it :-).
