How Mindomo DSA Licence Activation Actually Works
Mindomo Desktop only validates keys through its built‑in licensing panel:
The “two‑block 8‑digit key” you receive (Study Tech key)
This is the Desktop Licence Block.
It is meant to be pasted directly into:
Mindomo Desktop → “i” icon → License Info → Validate
Mindomo is extremely strict — even a missing newline or space breaks validation.
Wrong licence type
Mindomo has:
Lifetime / Premium Desktop licences - Likely not from Study Tech, may work online
Education / Cloud licences - not from Study Tech
DSA supplier-issued blocks - From Study Tech almost definitely
Only Desktop‑compatible keys activate the app. Mindomo has two fundamentally different licence types, as above.
Not all licence keys will validate online, any Study Tech supply in theory should in the downloaded app.
Some school networks block Mindomo’s activation endpoint. this WILL result in an invalid license message, not a connection error in some instances. It is recommended to try a non Uni connection and potentially, non Uni user profile on WIndows/Mac to see if the error persists.
Windows install and validate.
Open the app → click the “i” icon → License Info”.
Paste the full licence block exactly as supplied (name, key, date). 4x4 digits or 5x5 digits.
Any missing spaces or formatting breaks activation.
Click Validate.
Mac install.
