The "Corrupt installation detected" error indicates that you
do not have rights to install software (Windows 2000/XP/Vista/7)

If you are running Windows XP/Vista/7-10 and are not the Administrator:

  • Can't save data files? Ask the Administrator to set Winfilm (assuming you used the default directory) as a shared directory. Or move Winfilm subfolders to Shared Documents or My Documents (be sure to adjust File Configuration Directories in FilmStar).

FilmStar has no 'beginning, middle and end'. There is no particular sequence that must be followed, except that film index symbols (fixed in the Free Version) must be defined before being used in a design.

Context sensitive help may be obtained at nearly any point in the program. Don't be afraid to browse. Examine all the dialog boxes and repeatedly press <F1> for explanations. To get up and running quickly try the following:

  1. In the File menu verify that FILM Archive Mode is checked.
  2. Click File...Open...FILM Archive (<Ctrl+F12>) and load FILM file BBAR.
  3. Click button Calculate and evaluate the spectrum.
  4. Click Optimize...Optimize (<Ctrl+O>) and refine the design for 10 iterations.
  5. Now calculate again and click Design...Review (<Ctrl+R>) to see the new design.
  6. Click Evaluate...Interactor (<Ctrl+Q>) to enable the FilmStar Interactor!!!

If any of this doesn't work, please contact us for help. The on-line reference manual is the same as the full version.

Vista/Windows 7 Installation

1. POSSIBLE MESSAGE... In reponse to This program might not have installed correctly we found no problem after clicking This program installed correctly.

2. LIKELY PROBLEM...If you get an Unexpected error; quitting message box when running FilmStar, you can disable UAC (User Account Control) or right click the link and select Run as administrator. Then select Allow. The next time the program will run normally.

More about disabling UAC: Vista, Windows 7

3. UNIMPORTANT PROBLEM...Vista/Win 7-10 omit the WinHlp32.exe viewer for *.hlp help files. This is no problem because FilmStar uses HTML help. There is one place, however, where WinHlp32 is accessed: pressing the '?' icon in the BASIC UserDialog editor. You will probably never do this, but just in case here is what happens: On accessing WinHlp32 for the first time you arrive at a Microsoft site informing you that the help is obsolete, but they'll let you view it anyway. We've uploaded Microsoft's help installers for your convenience: 32-bit help installer, 64-bit help installer for newer computers. If you download from the Microsoft site, note that '64' indicates the 64-bit installer and '86' the 32-bit installer.


DLS 'ActiveX component can't create object' error

If you get the above error during DLS optimization, it's because math library matrix30.dll was not registered during installation. Although we don't know why this (rarely) occurs on some computers, it is easily fixed. Close DESIGN and click the Windows Start button followed by Run; then type

regsvr32 c:\Winfilm\Matrix30.dll

and click OK. You should get the following message

DLLRegisterServer in c:\Winfilm\Matrix30.dll succeeded

Vista/Windows 7 users need to deactivate UAC (User Account Control) or run regsvr32 as Administrator. Click Start.. All Programs.. Accessories and right-click Command Prompt followed by 'Run as administrator'. Then type the regsvr32 command given above followed by <Enter>.

If FilmStar is installed in a different directory, adjust the statement accordingly. Please let us know if this does not fix the problem.

Click here for information about restoring the Run command in Vista/Win 7. You can also use shortcut key <Windows +R>. Remember, however, that UAC must be disabled in order to execute regsvr32 from the Run command.



The FilmStar Free Version may be uninstalled via Control Panel. If you intend to purchase FilmStar, there is no usually need to uninstall.

In some instances (corrupted installation) it might be impossible to uninstall via Control Panel. In that case, rename or remove the Winfilm directory (first backing up files you want to keep) and delete the FTG Software key from the Registry.

or in 64-bit Windows

After reinstalling FilmStar you can transfer data and configuration files to your new Winfilm location. Registry operations are at your own risk.


'OLE2.DLL is not a valid Windows image' error

The following message appears at the end of the installation routine:

The application or DLL C:\Windows\System32\OLE2.DLL is not a valid
Windows image. Please check this against your installation diskette.

This is a known anomaly that rarely occurs during the dynamic link library (DLL) self-registration process at the end of the install routine. The message does not necessarily indicate that an actual installation error has occurred.

If an actual error happens during DLL self-registration, you will see much more specific error messages during program operation. In that case, please contact FTG Software and include the exact error message.
