we are a company of 200 people so multiple user accounts is a given. i am using a maintenance account with full admin privs.
last try was installing cs5 with 5.0 matrox software as that does work in our two other edit suites. CS5.51 seems to be the troublemaker. it’s particularly frustrating that after effects works fine
The Matrox folders are located in the presets location on the drive but do not appear in the Premiere UI
