Solution for Igor Pro 7 Windows File Open/Save Dialog Crashes

Several users have reported crashes on Windows while using Igor Pro 7 (64-bit). These crashes occur when a system file open or file save dialog is presented, such as when using any of the File→Open or File→Save menu items. The crash could also occur when any built-in command that presents such a dialog, including Open or LoadWave, is called.

This crash is caused by an interaction between Igor Pro 7 and the Dell Backup and Recovery application, which comes pre-installed on many Dell machines.

If you are not using the Dell Backup and Recovery application (in our experience, this is usually the case), we recommend that you uninstall Dell Backup and Recovery and then reboot your machine.

If you are using the Dell Backup and Recovery application, you may be able to continue using the application with Igor Pro 7 if you disable two extensions that Dell Backup and Recovery adds that cause the crash. To do that, download ShellExView from NirSoft. Run ShellExView and disable the following extensions:

  • DBROverlayIconBackuped.DBROverlayIconBackuped Class
  • DBROverlayIconNotBackuped.DBROverlayIconNotBackuped Class

Then reboot your machine.

We have not tested different versions of Dell Backup and Recovery to determine whether this problem is present in all versions or only certain versions.

Igor Pro 6 Font Issues on macOS 10.12 (Sierra)

We've come across two font related issues with Igor Pro 6 on macOS 10.12 (Sierra) and have developed workarounds for both problems. Neither problem is present in Igor Pro 7, so if you haven't already upgraded to Igor Pro 7, you may wish to purchase an upgrade.

Problem with Arial font

If you use Arial font in Igor 6 on macOS 10.12 (Sierra), Igor displays "unicode conversion error" instead of the correct text in graphs.

This affects both the English and Japanese versions of Igor 6.


  1. Purchase an upgrade to Igor 7 which does not have this problem.
  2. Use a different font.
  3. Drag the Arial.ttf font file from /Library/Fonts to some other folder for safe keeping and restart your machine. Igor 6 will use Geneva in place of Arial.
  4. Drag the Arial.ttf font file from /Library/Fonts to your desktop and restart Igor. Igor will display blank text for Arial. Quit Igor and drag Arial.tff back into /Library/Fonts and restart your machine. Arial now works correctly in Igor. This workaround may not be reliable or durable, though I have not seen it to fail in limited testing.
    Workaround #4 works for ASCII characters only. It does not work for non-ASCII characters (accented characters, math symbols, ...). For non-ASCII characters, you need to use workaround #1, #2 or #3.
  5. Drag the Arial.ttf font file from /Library/Fonts to some other folder for safe keeping. Replace your Arial.ttf file in /Library/Fonts with an Arial.ttf file from C:\Windows\Fonts on a Windows machine and restart your machine.
    Workaround #5 works for ASCII characters only. It does not work for non-ASCII characters (accented characters, math symbols, ...). For non-ASCII characters, you need to use workaround #1, #2 or #3.

Problem with controls

Controls, such as SetVariable controls, created with a default font setting in Igor 6J (Japanese) on macOS 10.12 (Sierra), display as very thin in the vertical dimension and are unusable.

This occurs because macOS 10.12 does not include Osaka font.

This problem does not affect the English version of Igor 6.


Install Osaka.ttf and OsakaMono.ttf in your /Library/Fonts folder. You can obtain these fonts from an older MacOS or download them from Apple. For downloading instructions, see

Igor Pro 6 and QuickTime for Windows

With the recently announced security vulnerabilities in QuickTime for Windows, some of our users have asked us to specify the Igor Pro 6 Windows features that require QuickTime for Windows to be installed. 


Two security vulnerabilities in QuickTime for Windows were recently discovered, and it is reported that Apple considers QuickTime for Windows to be deprecated and will no longer provide security updates for this product. The only mitigation to these newly discovered vulnerabilities available is to uninstall QuickTime for Windows. Apple provides instructions for doing so on its Uninstall QuickTime 7 for Windows page.


Igor Pro 6 on Windows optionally uses QuickTime to provide additional features related to loading and saving some types of sound, image, and video files. Specifically, QuickTime is required on Windows for the following features:


  • Importing image files of the following types using the ImageLoad operation or the Load Image dialog: PICT, GIF, Photoshop, Silicon Graphics, BMP and Targa.
  • The ImageFileInfo operation. Because this operation requires QuickTime, it will return an error if QuickTime is not installed.
  • Saving image files using the ImageSave operation except for raw PNG and TIFF files without color tables. The /IGOR flag must be used in order to save TIFF files when QuickTime is not installed.
  • Saving a picture file representing an Igor window using the SavePICT operation or Save Graphics dialog with the /T flag. SavePICT without the /T flag does not require QuickTime.


  • Loading and saving sound files using the SndLoadSaveWave XOP that ships with Igor Pro 6 requires QuickTime on Windows. This XOP provides the SndLoadWave, SndSaveAIFF, SndSaveWAV operations and LoadWAVfile and SaveWAVfile operations. If you uninstall QuickTime, you can load simple .WAV files into Igor 6 using the LoadWAVfile.xop. To use LoadWAVfile.xop you must first remove SndLoadSaveWave.xop.


  • Creating QuickTime movies using NewMovie. NewMovie can create AVI movies on Windows if the /A flag is used. Creating AVI movies dos not require QuickTime.
  • Playing any type of movie within Igor Pro using the PlayMovie operation requires QuickTime. However, the PlayMovie operation is able to open movie files outside of Igor Pro in your default movie viewing program, which is typically Windows Media Player.

The above information about Igor Pro 6 applies specifically to Igor Pro 6.37 and later. Prior versions of Igor Pro 6 may use QuickTime for Windows in slightly different ways. Igor Pro 6.37 is a free update to all Igor Pro 6 license holders. The latest version of Igor Pro can be downloaded from


The 64-bit version of Igor Pro 6 and all versions of Igor Pro 7 Beta do not and have never used QuickTime for Windows to provide any functionality. Also, the QuickTime for Windows installer prevented installations on a machine running Windows 10. Therefore, if you are using Windows 10 or one of the versions of Igor Pro that does not use QuickTime for Windows at all, your use of Igor Pro should not be affected if you choose to uninstall QuickTime.

Igor Pro 7 Beta provides built-in support for some of the features for which Igor Pro 6 requires QuickTime for Windows. If you only need these features, you may wish to sign up to be a beta tester for Igor Pro 7 Beta. Specifically, Igor Pro 7 Beta supports:

  • Importing BMP image files using ImageLoad or the Load Image dialog
  • Saving image files as JPEG, TIFF, PNG, and raw PNG using the ImageSave operation (the /IGOR flag is no longer required)
  • Loading and saving sound files using the new built-in SoundLoadWave and SoundSaveWave operations

Igor Pro 7 Beta Progress Report 2

Today we released another beta version, Igor Pro 7 Beta 5, and more than doubled the number of testers in our beta program. We took a pause from new releases over the holidays, but we've been busy fixing bugs and adding some new features during that time.

If you have signed up to be a beta tester before today (at and you haven't received an email with information on how to access the beta version, one of the following has probably happened:

  1. Our email to you got caught up in a spam filter somewhere. Invitation emails come from Please check your spam/junk mailbox to see if the message is there. Also, please make sure that you've added to your whitelist or contacts list so it doesn't get blocked in the future.
  2. The serial number/activation key you provided on the signup form wasn't for a valid license. In order to be a beta tester, you must have provided information for a valid Igor 6 English license that is registered to or associated with you or your institution. Special Coursework licenses are not considered a valid license for purposes of the beta test unless the license is registered to the user who signed up to beta test. If you're using a pirated license, someone else's license, or you're a student using a Special Coursework license, you're not eligible to be a beta tester.

If you've only recently received an invitation to be a beta tester, we thank you for your patience. We've had overwhelming response to the beta program and wanted to make sure that we're able to keep up with bug reports that come in from current beta testers before we add new testers.

Igor Pro 7 Beta Progress Report 1

It's been just over a month since the beta program for Igor Pro 7 started, and I thought I'd report on some of the progress that we've made.

So far we've released 3 beta versions, with Igor Pro 7 Beta 4 released today. Each beta release represents over 150 changes, many of which are fixes for bugs and crashes reported by our beta testers.

Speaking of beta testers, you guys and gals are awesome! Over 25% of you have directly contacted us to provide feedback or ask a question. We appreciate your feedback, and Igor Pro 7 has greatly improved because of your suggestions. If you're a beta tester and haven't been in touch, we'd love to hear about your experience using Igor Pro 7 Beta.

As of today, we've added more than 250 new beta testers to the Igor Pro 7 Beta program. This almost doubles the number of beta testers, and we still have hundreds more that have signed up to be testers. For those of you who have signed up to be beta testers but have not yet been invited to try Igor Pro 7 Beta, we appreciate your patience.

If you haven't done so already, now is a great time to purchase your Igor Pro 7 upgrade while it's still available at our current pricing. Igor Pro also makes a great holiday present for any of your friends or family members who love analyzing data and making beautiful plots.

Igor Pro 7 Beta Testing Has Started

I'm excited to announce that we've officially started the beta testing program for Igor Pro 7. All of our original technology preview testers who signed up to be beta testers, as well as several new testers, have all been sent an email with information about how to access Igor Pro 7 Beta.

We'll be slowly inviting additional users to the beta program so that we're able to remain responsive and fix newly reported bugs quickly, so if you haven't already received an invitation, we haven't forgotten about you. Thanks for your patience!

If you haven't signed up to beta test yet, we're still accepting signups for beta testers on our Be A Beta Tester page.
