Inodb table now myisam after reinstall on upgraded w10

[Ron Nuberg]

Upgraded from Windows 7 Ultimate to Windows 10 Pro, removed my WAMP installation and other software.
Reinstalled WAMP, adjusted root password, added extra users and set innodb_file_per_table=1;
Now when I browse my tables using phpmyadmin, some tables I can see the data, but some say table not found, while when I look in the folder the old database files are still there.
Within phpmyadmin i see that the tables which give an error are now myisam, while i know for sure that I created them as inodb. the data that is shown where myisam before!
On my laptop which still runs windows 7 and where I have a copy of the tables they are also inodb.
With Dbase II and III, I knew which bytes of a file made up the database definitions, also Ingres database files, I once knew how to create them from my software. But reading and searching the web I am unable to find how mysql determines if a file is myisam or inodb or even better how to change the incorrect system table information from myisam to inodb?

Thanks

Ron
