Error during installation? Phoca Cart 5.2.2 into J 5.4

[Shuffle]

Just a hint!
I tried to install Phoca Cart 5.2.2 (J 5.4) and got this error:
---
Jlnstaller: :Install: SQL Fehler BLOB/TEXT column 'alias_value' used in key specification without a key length
Die Installation der Erweiterung wurde gestoppt
Paket installieren: Bei der Installation der Erweiterung trat ein Fehler auf: com_phocacart_v5.2.2.zip
---
So I took Phoca Cart 5.2.1 - installation was fine with no error - update to 5.2.2 works also fine.
Don´t know, what the message above means.

Cheers!
