no i'm getting output errors:

i'm facing bit of learning curve ps , had script reading so far.

i see main issue print debug line: quotes gone already. , manager told me invoke-expression not idea. recommends me use start-something

now i'm stuck. pointer appreciated , there upvotes well.

add -erroraction stop inside try/catch, should trigger desired action:

try{     ...     invoke-expression ($importtoolexe + " " + $params) -erroraction stop     ... } catch{     ## catch code } 

you can try invoke-command start exe in scenario replace invoke-expression following:

invoke-command -scriptblock {&$importtoolexe $args[0]} -argumentlist $params
