Stop Feature upgrade if precheck fails

[lalajee]

Hi,
I'm using an action custom script to run a Powershell script to check for a few things before running the feature upgrade on a machine but even the machine is not compliant it still running the upgrade.

 

for example, I have this code in preinstall.cmd/preinstall.ps1

if(-not (Test-path $path))
{
write-error "Stop"
exit 1

}

this should stop the upgrade but its not happening.

Does anyone know how I can stop the upgrade if it doesnt meet my preinstall checks
