Take a look at the log file to find a more specific error: C:\Users\christoc\AppData\Local\Temp\WindowsAzureToolsInstall.txt. Error code -2147023293, which means a fatal installer error, is too generic.

Also, you can try invoking the cached installer manually: C:\Users\christoc\AppData\Local\Microsoft\Web Platform Installer\installers\WindowsAzureToolsOnlyVS2010\580DFFB79499C7427AD38C84E632FFFF39C3FBCC\WindowsAzureTools.VS1007.exe. This would actually launch the installer with the UI, so it can give you more hints on the failure.
