Crashes when opening

Analog Efex Pro 2 crashes when I try to open it. Or, my image is missing, there is a color cast over the image, or the image is extremely pixelated. How can I resolve this?

Analog Efex Pro 2 takes advantage of the Graphics Processing Unit (GPU) of the computer system. The GPU is also sometimes referred to as the Display Adapter or Video Card, in any case they are all the same. Sometimes certain video cards will not handle this additional processing, and crashing may be a side effect. Please choose your operating system below for more information on how to resolve this issue.

Mac Users

In order to resolve this, the first measure would be to update the Display Adapters or GPU driver.

Generally the video card that comes with your Mac will be updated automatically. The exception may be when there has been an additional video card added. In that case the user may need to go to the video card manufacturer's website to download an updated driver for their secondary GPU. If you are using Mac OS Snow Leopard (10.6) ensure to update to 10.6.6 or higher as this can affect performance. If this does not apply to you, please go to the next section below.

If after following the above steps you are still experiencing the same issue, the next step will be to disable the GPU (if possible). In order to disable the GPU in Analog Efex Pro 2 please do the following:

  1. If you are able to open Analog Efex Pro 2 and can see part of the interface, see if you can click on the"Settings" button in the lower left.
  2. In Settings locate the section "GPU" and expand it, in this section you will see a check box "Enable GPU Processing", uncheck this so the GPU will be disabled, then close the settings window.
  3. Close out of Analog Efex Pro 2 (click Cancel), quit out of any and all host applications (Photoshop, Lightroom, Aperture), and then relaunch Analog Efex Pro 2 to see if this corrects this issue.

If you are unable to disable the GPU via Settings or if the issue is still unresolved (e.g. Analog Efex Pro 2 crashes or the buttons are not displaying correctly), please contact our technical support for further assistance.

Windows Users

In order to resolve this, the first measure would be to update the Display Adapters or GPU driver.

Locate the manufacturer of the GPU as well as the model number. Once this is determined, it is then recommended to go directly to the GPU manufacturer's website (best option) or if that is not possible to go to the computer manufacturer's website (secondary option) to obtain an updated video card driver. It is NOT recommended to use Windows Update as in general we have found that these drivers are not updated as frequently. To identify which video card you have, please do the following:

  1. Click on Start >Control Panel>System & Security >System >Device Manager and then click on the plus next to Display Adapter, this should display the make and model information.
  2. Go to the manufacturer's website (you may need to search for it via Google) such as Nvidia.com and with the model number you should be able to search for the latest driver. If you are unable to locate the driver you may need to contact the manufacturer of your computer to obtain an updated driver.
  3. Once the latest GPU driver is located,download and install the new driver.
  4. Restart the computer and try Analog Efex Pro 2 once again.

If after following the above steps you are still experiencing the same issue, the next step will be to either disable the GPU (if possible) or force Analog Efex Pro 2 to not use the GPU (safe-mode). In order to disable the GPU in Analog Efex Pro 2, please do the following:

  1. If you are able to open Analog Efex Pro 2 and can see part of the interface, see if you can click on the"Settings" button in the lower left.
  2. In Settings locate the section "GPU" and expand it, in this section you will see a check box "Enable GPU Processing", uncheck this so the GPU will be disabled, then close the settings window.
  3. Close out of Analog Efex Pro 2 (click Cancel), quit out of any and all host applications (Photoshop, Lightroom, Aperture), and then relaunch Analog Efex Pro 2 to see if this corrects this issue.

If you are unable to disable the GPU via Settings or if the issue is still unresolved (e.g. Analog Efex Pro 2 crashes or the buttons are not displaying correctly), please try the following steps below after quitting out of all host applications (Photoshop, Lightroom, Aperture):

  1. Click Start and type in the search box %localappdata% (exactly as shown with % symbols on each end. When the yellow folder "Local" is displayed in the search list, click on it. If you are on Windows 8, press the Windows key + R, search for %localappdata%, and press the Enter key.
  2. The local folder will open, now double-click on "Google" followed by "Analog Efex Pro 2" and locate the file AnalogEfexPro2.cfg and then double click to open. Windows will ask you which application to use to open this file, locate and choose "Notepad"to open.
  3. At the very beginning (before all the text) of the configuration file, paste the following code below verbatim:
    <configuration>
    <group name="INTERN">
    <key name="UseSafeMode" type="bool" value="1"/>
    </group>
    </configuration>
  4. Now save the file, close it and relaunch Analog Efex Pro 2 to see if the issue has been resolved.

If the issue is still unresolved (e.g. Analog Efex Pro 2 crashes or the buttons are not displaying correctly), please contact our technical support for further assistance.
