I installed Antares AutoTune 4 (AT) Direct X Plug-in, onto my XP SP2 PC and it wont run. Have you any experience here to give me some advise on how to fix?. Here are the particulars: I have two multi track apps.....Power Tracks Pro (PTP) and Adobe Audition (AA). In PTP the program crashes when starting the AT plug-in. In AA it will eventually show Autotune Plug-in as a unsupported application. For a test I installed AT and AA on another PC and Autotune worked fine.....so something is not right about my PC I guess. An older version of Autotune (3) used to work on this PC before Installed version 4. Now when re-installing version 3 it has a failure during its install. It give an error message of something like Glj2.tmp failed during the install. I tried a restore to a week ago and the problems are the same. Any hints appreciated.
