Remove or replace a computer

Short answer: On your account page, open Your computers and choose Remove on the computer. Its place frees immediately. The Litesum applications on that computer keep working until their current licence runs out — at most seven days — and then stop saving and exporting. Nothing on the computer is deleted.

Steps

1. Sign in at account.litesum.com and open Your computers.
2. Find the computer. Two computers can have the same name, so check the short id, the platform and the dates.
3. Choose Remove, then Yes, remove on the confirmation.
4. To replace it, activate the new computer as in Activate a computer.

Why it keeps working for a while

Each computer holds a signed licence valid for up to seven days between online checks. Removing the computer from your account cannot reach a licence already issued to a disconnected machine, so the applications there run until that licence expires and cannot renew. That is the actual behaviour, stated plainly rather than promised as instant.

Reinstalling Windows

A reinstalled computer counts as a new one. Remove the old entry, then activate afresh.
