Thank you again for your answer.
As I said before, I don't know much about coding.
As you said, I thought there might be a problem due to the "space" in the window title.
Based on this, I tried to handle the "percentage" part and the code gave positive results.
The working code is below.
<VARIABLE SET INTEGER Option="\x00" Destination="%N[1]%" Value="0"/>
<REPEAT UNTIL Variable="%N[1]%" Condition="\x00" Value="1"/>
<IF WINDOW Option="\x01" Title="100% tamamlandı" Partial="TRUE" Wildcards="TRUE"/>
<VARIABLE SET INTEGER Option="\x00" Destination="%N[1]%" Value="1"/>
<DELAY Flags="\x01" Time="2"/>
<END IF/>
<DELAY Flags="\x01" Time="10"/>
<END REPEAT/>
<POWER OFF COMPUTER _ENABLED="FALSE"/>
I would like to thank all my friends who responded and tried to help.
Respects
