thank you :-) , i could run the mod using ZDL :
"Download ZDL from one of the links provided here: https://zdoom.org/wiki/ZDL
- In ZDL's Source ports section of the "General settings" tab, use the Add items (+) button to add DOOM64_x64.exe from the Doom 64 folder as a source port.
- In the IWADs section of the "General settings" tab, use the Add items (+) button to add DOOM64.wad from the Doom 64 folder as an IWAD.
- In the "Launch config" tab, either drag and drop the wad in the "External files" section or use the Add items (+) button to add it.
- Then in the "Source port" section, select the source port you added previously, and in the "IWADs" section select the recently added IWAD.
- Click on the "Launch" button to run The mod".
