Show-InstallationProgress -StatusMessage 'Uninstalling application [$installTitle]. Please Wait...'

above line should had shown me thi

Variables: Application

[string]$appVendor = 'Igor Pavlov'
[string]$appName = '7-Zip'
[string]$appVersion = '9.35 beta'
[string]$installTitle = "$appVendor $appName $appVersion"

but i getting the this:

I put '' around the [$installTitle] and got this error
Error Inner Exception(s):
