Cannot install Azure/AzureRM PowerShell modules on Worker roles

Question

I have a Worker roles on Azure Cloud service (classic) and I want them to install Azure and AzureRM PowerShell modules on startup. I've added a startup task in my ServiceDefinition.csdef file:

<Startup>
  <Task commandLine="InstallAzureModules.cmd" executionContext="elevated" taskType="simple" />
</Startup>

InstallAzureModules.cmd file looks like this:

PowerShell.exe -ExecutionPolicy Unrestricted .\InstallAzureModules.ps1 >> "D:\InstallAzureModulesLogs.txt" 2>&1

And InstallAzureModules.ps1 looks like this:

Install-PackageProvider NuGet -Force

Install-Module Azure -AllowClobber -Force

Install-Module AzureRM -AllowClobber -Force

In result I have an error There is not enough space on the disk, however when I connect to any Worker instance using Remote Desktop and run InstallAzureModules.cmd manually all modules are installed without any errors.

Please help to have these modules installed.

Thanks.

Finally after contacting Microsoft Support the issue was resolved!

According to Support Professional who was working with my request this error is due to a redirection of application temporary folder. I was recommended to go through this link for a possible fix, but it didn't work.

Also updates to my PS script were provided and what actually helped was setting TMP and TEMP environment variables to a folder on drive C. So here is my final script:

$env_TMP = $env:TMP
$env_TEMP = $env:TEMP
$env:TMP = "C:\_trashable\Modules"
$env:TEMP = "C:\_trashable\Modules"

Install-PackageProvider NuGet -Force

Install-Module Azure -AllowClobber -Force

$env:TMP = $env_TMP
$env:TEMP = $env_TEMP

ECHO "Finished"
