i extracted the one file in the .zip, deleted the original Peggle.exe and renamed the extracted file, though Peggle won't open through Steam or through the installation folder. when playing through the installation folder, the "This app can't run on your PC" error message appears. any tips?

even though it's outdated, I used this version of the guide and it went without a hitch, hopefully it should work for you https://www.speedrun.com/peggle_deluxe/guides/ko3uj

also make sure to grab this version of the no pause mod: https://www.speedrun.com/peggle_deluxe/resources/z2l2l
