I recently wanted to install the Windows Azure SDK 2.0 on my development laptop, but the usually-pretty-good Web Platform Installer was having none of it:
Well… that’s unhelpful
Luckily WPI gives us a log file during installation that might help. Taking a quick shufty, we find where the problem is pretty quickly:
DownloadManager Information: 0 : Starting EXE command for product 'Windows Azure Emulator - 2.0'. Commandline is: '[removed for brevity]\WindowsAzureEmulator-x64.exe /quiet /norestart /msicl RUNDSINIT=1 /log C:\Users\<Username>\AppData\Local\Temp;C:\Qt\Qt5.0.2\5.0.2\msvc2012_64\bin\WindowsAzureEmulator_2_0.txt'. Process Id: 5264
DownloadManager Information: 0 : Install exit code for product 'Windows Azure Emulator - 2.0' is '1622'
So – the process is exiting with code 1622, but hold on – what the hell’s that log path? It starts looking like a reference to the temp directory, but with the Qt install path involved? Let’s look at what %TEMP%’s set to:
C:\Users\<Username>>echo %TEMP%
C:\Users\<Username>\AppData\Local\Temp;C:\Qt\Qt5.0.2\5.0.2\msvc2012_64\bin
As they say – there’s your problem. Removing Qt from the %TEMP% environment variable and we’re off.
