I KEEP GETTING THE ERROR MESSAGE “EXPECTED A KEYWORD OR AN OBJECT NAME” WHEN STARTING IGOR PRO. WHAT DO I DO?

You may encounter a ‘Function Compilation Error’ message that looks like the one below when launching Igor Pro:

one_drive_error_1

This error usually occurs because Iolite cannot find the EasyHTTP.xop file in the Igor Extensions folder. To solve this issue:

  1.  Quit Igor Pro
  2. Move the EasyHTTP.xop file from the iolite v3.32 download folder to:

Documents/Wavemetrics/Igor Pro User files/Igor Extensions

You should be able to launch Igor Pro without any issues now.

If the problem persists after you have moved the EasyHTTP.xop file to the correct location, please try one of the following troubleshooting steps:

Some Mac users have reported issues with the EasyHTTP extension not working. To fix this, just rename the easyHTTP_MAC.xop file to easyHTTP.xop.

For PC users, it is possible that the  issue may be caused by a conflict with OneDrive’s automatic file saving options. Please quit Igor Pro and check your auto-save settings in OneDrive:

  1. Right-click the OneDrive icon on the Notification Area and click on ‘Settings’.
  2. On the Auto-Save tab, choose to save Documents to “This PC Only”.one_drive_error_3
  3. Click ‘OK’ and restart Igor Pro. Iolite should start correctly now.
