Well, the thing is i'm trying to properly install AIMP2 to my windows. Everything is going well till now, the only thing i lack is that AIMP needs to be Run once in order to run correctly. It associates all the file extensions now, as i want it to do but... it doesn't open files unless i manually open it once. After that, it works flawlessly for all users. I've tried running aimp and closing it using tskill but the thing is once i run the command, it waits for aimp to be closed. "%programfiles%\AIMP2\AIMP2.exe" tskill AIMP2 /a "%programfiles%\K-Lite Codec Pack\Media Player Classic\mplayerc.exe" tskill mplayerc /a It doesn't run line 2 unless one closes aimp2.exe and that just sucks. Then i tried "%programfiles%\AIMP2\AIMP2.exe" | tskill AIMP2 /a "%programfiles%\K-Lite Codec Pack\Media Player Classic\mplayerc.exe" | tskill mplayerc /a And that doesn't work as well. Can somebody give me a clue how to do this, please?
