I run Quickbooks 06/07 on Windows XP. It was working fine yesterday! Today, the error message !szFileBuffer.empty( ) appeared. And then another error message: Microsoft visual C++ Runtime Library Runtime Error! Program:C:\ProgramFiles\Intuit\Quickbooks\qbw32.exe This application has requested the runtime to terminate in an unusual way etc I found a similar problem and answer on this site (thanks guys) that said to uninstall and reinstall. Did that but the same messages still appear. Any other suggestions gratefully accepted - thanks.
