Just got a new computer with Windows 10 home on it and I cannot start Calamus without having to enter the match code every time in order to register. Then Calamus will not save the data?
Any ideas anyone?
Also I cannot find the upxxxxxx.dat anywhere... Maybe because it won't save the registration?

AFAIK, the match code is stored in the system dir (inside the Calamus dir) under the name calamus.key.
I don't have an upxxxxxx.dat file at all. That's with SL2015.

HTH,
Martin

Please don't install Calamus into the Windows Program folder, but - as the installer suggests - simply into C:\Calamus\SL20xxnn\, where xx stands for the year and nn for the language. If you can copy your files from your old computer, the match code registration file is in C:\Calamus\SL20xxnn\System\CALAMUS.KEY.

If these steps don't work, please send me an email.

As Steve and I found out, he had installed Calamus SL 2015 properly into the expected directory. But somehow it caught some kind of write protection so that Calamus was unable to store the registration key into its System folder.

PS: The UPxxxxxx.DAT file is not related to the Calamus registration but is created by the Version Checker module and should be uploaded in "My Calamus: My Version Check".
