Common questions
Where is my license key?
On the Lemon Squeezy order page and in the receipt e-mail. Can't find it? E-mail us with the address you bought with.
How do I activate it?
See activating a license. It needs the internet once.
I have a new computer
E-mail us with your order number and we will move your license to the new computer.
My free year ended - is my work lost?
No. MathSheet keeps opening and printing your worksheets. Enter a current license key to edit and save again.
Windows warned me when I started the installer
Please do not override the warning. Check the publisher: our installer is signed by Sheetwise Engineering LLC. SmartScreen can still warn about a new release that few people have downloaded yet. Delete the file, download it again from the Download page, and check its checksum (how). If the warning stays, e-mail us and we will help.
Can I open worksheets from another program?
Yes, .xmcd files: File › Import worksheet (.xmcd). See import for what comes across.
When you e-mail about a problem
Please include the MathSheet version (Help › About), what you did, and if possible the worksheet file.
