You backed up your quicken 2000 on Windows 98SE and tried to restore it to new Quicken 2010 Deluxe on Windows XP. Quicken 2005 was on the XP computor and you removed the software. 2010 shows QDATA BACKUP-1.1.06QDF.
An ERROR message appears saying Authentication of convert-stub.dll failed because it could not find required file. Please reinstall Quicken to convert your data file. Reinstallation does not help. Now what do you do?
Can you please first try to update your version of Quicken 2010. Go to the Help menu in Quicken and have the program download and install any updates. Also, you might need to perform some file cleanup ie. delete duplicates in the memorized transaction list if thats necessary.
Another option would be to remove Quicken 2010 Deluxe and then reinstall your version of Quicken 2005 if possible. Then try to convert the backup data into the 2005 version. If successful you would then create another backup using Quicken 2005. Obviously you would save that backup and reinstall Quicken 2010 deluxe and try to restore the backup data from the Quicken 2005 backup file.
Can you try to make sure all files of your old data set QDF, QEL, QPH, etc. are copied I repeat copied to the folder where your Quicken installation expects the final files to be. Then double click on the qdf file. Quicken should launch and offer to convert the data.
You could also download an intermediate trial copy of Quicken in order to use just to convert a backup that will be recognised by Quicken 2010. I found trial versions for Quicken 2001, 2002, and 2008 via the following links. Quicken allows downloads of older trials for this purpose.
