Hello uweraj,

Thank you for reaching out. If your Student version has expired before the 14 months have lapsed, the reason for this may be that Sage 50 Canadian is detecting a previous install of Sage 50 Canadian on your computer. Please follow the steps below to correct the issue:

1. Uninstall Sage 50 Canadian Student Version

2. Go to http://simplydownload.accpac.com/downloads/SimplyAccounting/students/StudentVerCleanUp.zip

3. Run the "Student Version Utility"

4. Re-install Sage 50 Canadian and Activate the program

Once you have completed those steps, your program should be up and running for you.

Hope this helps!
