Uninstallation error

1: CCAV version:
1.8.407941.426

2: OS version:
Windows 7 Home Premium SP1 64bit

3: What you did:
I was trying to uninstall CCAV. When it asked me to enter some feedback, I skipped it.

4: What you actually saw:
Uninstallation was stopped at 43% and it gave me an Error code 2203 message.
I repeated the procedure and entered some random text in the box. After that, uninstallation was completed successfully.
It already happened twice, in last two versions.

5: What you expected to happen or see:
Even if I do not enter any text in the feedback box, uninstallation procedure should be completed with no error.

6: If possible attach a screenshot illustrating the GUI problem
Screenshot attached.

Please check again with version 1.9 build 469. Thanks.

Still not fixed with CCAV 1.10.
