I installed Antares AutoTune 4 (AT) Direct X Plug-in, onto my XP SP2 PC and it won't 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 plugin . 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.
