    The Expected data should be one of the following types:

02/25/2026yukiOriginlabHi shaolin.liu,
If you downloaded the app from our website, please check your Downloads folder.
If you installed it from the App Center, Origin will automatically install it after the download is complete. You can usually find the app in the App Gallery docked on the right panel. Please look for the app icon there.

01/09/2017hideo fujiiHi ankitiiser, If you want to run this tool just for your current work temporarily, you can run the evaluation version of Origin 2017, downloaded from: http://www.originlab.com/demodownload.aspx . The evaluation version can coexist with your product version of Origin. --Hideo Fujii (OriginLab)

Thank you
Kindly mail me the version suitable for this.
