Hello Thausand,
it seems that TProcessEx class has gone from the processutils.pas since April 2020. The last processutils.pas file with TProcessEx class is here
In my project, i use a processutils.pas older than this one (2018)
Ok, thank much for explain Jurassic Pork.
I get why is missing and me no blind is joy

if you want to know the reason why TProcessEx has gone, ask the question to DonAlfredo in the forum ThirdParty/fpcupdeluxe
Not real important and know why. Program make evolve and change. I Think I try last version for improve/upgrade code then there nothing. Now I try with you attachment. Very many thank.
