Downloading/Installing Software on Windows FAQs

If you experience issues when downloading or installing software on Windows please check the list of systems below to find the resolution for these issues: 

Symptom: Error message “Can’t open file for writing.” or “The disk is full trying to write to…”

Check free disk space. The Leap Motion software can use up to 400MB even with no apps installed. If free disk space is less than 400MB, try freeing up some disk space: Clear the folder “C:\Windows\Temp” or empty your Recycle Bin.

Symptom: The download fails when using Internet Explorer 7, 8 or 9

Use another major browser (e.g. Chrome, Firefox, Safari), or upgrade to IE 10+.

Symptom: The setup file is not recognized by Windows

Check the file to see if the file has an .exe extension, and rename it to add the .exe if it’s not there.

Symptom: Disk image can’t mount, with error “corrupt file”

The setup file that you have downloaded may have not completed successfully or was corrupted. Please try redownloading the latest installer from leapmotion.com/setup.

Symptom: The download for the Leap Motion software stops shortly after download

If you have any anti-virus software running, try temporarily disabling it before downloading Leap Motion software. Some anti-virus software (such as Avast!) may think it’s a virus/malware and prevent it from being downloaded.

Symptom: MSCVP100.dll or MSVCP120.dll is missing or corrupt
