QAssistant won't start

[David McKenna]

After installing the new QT 4.6.2 (all components -dev, doc, examples, lib) QAssistant will not start. There is an error message "cannot load sqlite database driver!".

I tried running assistant_adp.exe. It starts, but gives a bunch of errors like: Documentation file C:/ECS/DLL/qt/doc/html/assistant.dcf does not exist! Skipping file. This is not where those files were installed by WarpIn.

Thank you for the report. This means that you most likely did not uninstall the previous version of Qt4 (upgrading the existing Qt4 installatioln is not supported due to WarpIn limitations). Please try this:

1. Uninstall all Qt4 packages.
2. Delete all qt*.conf files you will find on the installation drive.
3. Reinstall Qt 4.6.2 WPIs.

Please report if it helps.

I did use WarpIn (ver 1.0.19) to un-install QT 4.5.1. But you are correct, there was one file: C:\ecs\dll\qt.conf left over from a previous installation. After removing that and re-installing 4.6.2 everything seems to work now. Thanks for your fantastic work!

Thanks for reporting back. Just for the record, qt.conf should have left from the beta installer -- 4.5.1 GA (and 4.6.2) uses a different file and therefore uninstalling 4.5.1 didn't delete this one. I may consider modifying the 4.6.2 WPI to delete this qt.conf file after installation to make sure it does not interfere with the new one.
