I have same error when installing:
The program Vopt.exe must be closed before continuing.
Please close the program and click Retry to continue.but the solution is simple, save installer to disk and rename it to somethning different than “Vopt.exe” (e.g. “Vopt-installer.exe”), because when it is named “Vopt.exe” installer detects running proces “Vopt.exe” and thinks that you have Vopt already installed and running.
