Entry point not found error
I downloaded the Sigil-0.5.0-Windows-x64-Setup.exe. Installation seemed to be fine. However when I attempted to start Sigil I received the following message, "Sigil.exe - entry point not found. The procedure entry point ??0QData Stream@@QEAA@PEAQBytes Array@@H@Z could not be located in the dynamic link library QTCore4.dll" I was previously running Sigil 0.4.2 successfully. I attempted uninstalling, redown-loading and reinstalling with the same result. I am using Windows 7 Home Premium with SP1 installed. A Intel Core i7 64 bit processor. 8 GB RAM.
Any ideas? Thank you in advance.
