Zenon 7 registration error with "ZenDbSrv is running" message

Hello, support team!
I try to switch into 7.00 SP 0 Build 5 on my windows 7 32 bit from 6.51 SP 0 Build 14 using Startup Tool.
During this process I get error window (see attachment), then Startup Tool finished its work.
How to start 7.00?
