I have the “PowerPoint could not open the file” issue when website run under IIS Application pool Identity NOT an Administrator User.
Everything okay under an Administrator User.
Unfortunately, Administrator User not feasible at the Production environment.
Is Administrator privileges mandatory for PowerPoint automation this way?
Please advise.
