Q: What should I do when I see this error message: "Unknown error. Program cannot set property into main Storage"?
A: This error message is displayed when your ODBC drivers are too old, or damaged, or if they aren´t installed properly. avast! uses these drivers by default.
* Don´t use the ODBC drivers, use XML instead. To make avast! use XML drivers, follow these steps:
1. Open the file avast4.ini located in C:\PROGRAM FILES\ALWIL SOFTWARE\AVAST4\DATA in Notepad.
2. Find the section [COMMON]
3. In this section, change the line
Database=ODBC to Database=XML
4. Save the file
5. Restart your computer
