Picture Window Troubleshooting

How can I determine my current version?

Picture Window displays its name and version number in the title bar of the main window. If you have the standard version, it will say Picture Window; if you have the pro version it will say Picture Window Pro . Following this is the version number -- the major version number followed by a period followed by the minor version numbers (e.g 7.0.13 ). The version number and other useful information is displayed when you select Help/About Picture Window (or Help/About Picture Window Pro ) from Picture Window's main menu.

What's the Latest Version? For information on the latest release of Picture Window Pro and Picture Window, click the link below:

Install Ltclr15u.dll to Read CMYK Images (PWP 5.0)

Ltclr15u.dll allows Picture Window to read CMYK image files and convert them to RGB. The DLL is not distributed with the download version, to keep the download small. (It is distributed with the CD version of the program.)

To install, download Ltclr15u.dll into your Picture Window folder. (Usually the folder path is c:\Program File\Digital Light & Color\Picture Window Pro 5.0). It will then be available for Picture Window to use.

Later versions of Picture Window automatically install this DLL.

MSVCR80.dll Error

Problem: MSVCR80.dll is a Microsoft DLL that is installed in the Picture Window Pro main folder. If you are using an older version of Windows, such as Windows 2000, you may receive the following message: 'MSVCR80.dll is not a valid windows image'. This message indicates that the version of the DLL is not compatible with your operating system.

Resolution: To resolve the problem, delete the DLL from you Picture Window folder. (Usually the folder path is c:\Program File\Digital Light & Color\Picture Window Pro 5.0) Picture Window will then search for a different copy of the DLL on your system.

"The application failed to initialize properly" Error

Problem: This error is generated by Windows when it fails to find a valid Microsoft .NET library on the user's computer.

Resolution: To resolve the problem, update your .NET library. You can download a free update from the following Microsoft web site:

Opening Raw Image Problem

Problem: When you open a raw image the raw dialog opens but the image area is blank. The error message "Can't create or delete read-only file" is displayed. The message refers to a failure to create a temporary file in the current temp folder. The problem is caused because the temp folder either does not exist or is write-protected.

Resolution: The temp folder used by Picture Window is set in File/Preferences. If no temp folder is set the default folder is c:/temp. Check if the temp folder as listed in Preferences (or the default folder) exists. Make sure that its permissions include reading and writing. Also make sure that space is available on the disk. This folder is used to back up open image windows, so there should be enough space for the number of images you have open simultaneously.

If the existing temp folder cannot be given read and write permission or is on a drive with inadequate free space, create a new temp folder on any other permanently-attached internal drive. It must be readable and writable. To create the new temp folder, go to File/Preferences and set the temp folder path by clicking the browse button and navigating to the new folder.

HTML Help Problem

Problem: When you invoke Help in Picture Window, the help system attempts to connect to the internet.

Resolution: The problem is most probably caused because the help program cannot locate HHActiveX.dll on your system. To correct this problem:

    1. Download HHActiveX.dll . Place the downloaded file in your Windows\System32 folder. (On Windows 2000 systems the folder is called WinNT/System32).
    2. Click on the Start button and select Run.
    3. Type regsvr32 <path>HHActiveX.dll and click Run to register the dll.

The help system should no longer try to connect to the internet.

Autoplay Problems (PWP4 and earlier)

Problems: The Autoplay menu is displayed when you insert a memory card or CD with images, but it does not list Picture Window Pro.

Picture Window is listed in the menu but does not run when you click on it. (The error message below may be displayed.)

Resolution: There may be a problem with how PWP is registered with Autoplay. To update Autoplay registry settings do the following:
    1. Download the PW.inf file at the end of this procedure.
    2. Display the file in Windows Explorer.
    3. Right-click on the file and select Install.

The registry will be updated, correcting the Autoplay error.

Please note: The .inf file assumes that you have installed Picture Window Pro 4.0 in c:\Program Files\Digital Light & Color\Picture Window Pro 4.0. If you have installed it elsewhere (or if your system does not use English) edit the pathname in the inf file to your actual installation folder. (The installation path appears in the inf file several times.) You can edit the file using a text editor such as Notepad.

Download PW.inf

Installation Problems How do I install an update?
To install a new version of Picture Window, just download the latest version from our web and install the new version over the old one. The new version will recognize your existing serial number. You can tell if a new version is available by comparing your version number to the version number listed on the Downloads page.

My download does not install.

One or more of the following may help:

1) Use the Add/Remove Programs control panel to uninstall all earlier versions of Picture Window 3.5 and delete the Picture Window 3.5 folder in C:\Program Files\Digital Light & Color.
2) Clear your browser cache (using Internet Explorer: Tools/Internet Options/General/Delete Files... )
3) Shutdown your computer and reboot
4) Temporarily disable your antivirus/firewall software

Missing file on install from the web

When installing from the web and electing to save setup.exe instead of running it, you may get a message indicating the the file Instmsia.exe or Instmisw.exe is missing when you subsequently run setup.exe. These files contain the latest versions of Windows Installer which are required to complete the installation. To download Windows Installer, visit one of the following Microsoft Web sites:

Instmsia.exe (for Windows 98 or Windows Millennium Edition):


Instmsiw.exe (for Windows NT, Windows 2000 or Windows XP):

These files are intentionally omitted from setup.exe to reduce the download size which would otherwise be about 2MB larger.

GDIPlus.dll File Is Missing

Some Windows 2000 systems may not have a copy of gdiplus.dll which is required by Picture Window. (The DLL has not been included in the installation because the majority of Windows systems already have a copy.)

To correct this problem, please download file. After downloading it, extract the gdiplus.dll and copy it to your WINNT\System32 folder. Picture Window should now start normally.

Enabling the Winzip Option

Zip archives of images and other files can be created directly from the Browse and Workflow windows. The feature requires that you have Wzzip, a Winzip command line processor, installed on your system. Wzzip itself is a free download and provides a command line interface to compatible versions of Winzip. You can download wzzip from Make sure to also check to see if your version of Winzip is compatible with wzzip.

Preview Problems

Preview windows can be zoomed and scrolled.

One of the most powerful and sometimes overlooked features of Picture Window is that preview windows can be resized, zoomed and scrolled using the same Window commands that are used for image windows. This gives you the flexibility to preview detail in a small part of an image or see an overview of the entire image.

What is causing my preview windows to look grainy?

What you are seeing is aliasing which results from the preview being computed only at the pixel locations on the screen. When the preview window is zoomed out to beyond 1:1 this means that some pixels in the output image are skipped and this causes the preview to look grainy. Normal image windows are antialiased to reduce this effect, but to antialias preview windows would mean it would take as long to compute the preview as it does to compute the final image so there would be little point in previewing.

You have three options:

1) Zoom the preview window to 1:1 -- this eliminates the aliasing artifacts.
2) Click the Apply button to create a full resolutionimage that will be antialiased.
3) Live with the grainy preview

You can turn off antialiasing for zoomed out image windows which will make image windows look as grainy as preview windows (via File/Preferences).

Printing Problems

Picture Window Pro crashes when I print color images.

A number of printer drivers do not fully support Windows color management and crash either repeatably or intermittently when passing image data that has an associated color profile. The only workaround at this time is to go to Picture Window's Help/Support Settings command and uncheck Print Using V5 Bitmaps. To get color management to work with this setting unchecked, you need to do one of two things:

1) Only print sRGB images.
2) Specify a custom profile for your printer whenever you print a non-sRGB image.
