Unexpected (Too old?) file format

[#1]

Hi everyone i am new at Qlikview i developed an application but now when i try to open it i get Unexpected (Too old?) file format error.

i am using Qlikview x64 Personal Edition

i am afraid to reinstall Qlikview Application because it may happen to same to the rest of the files because of a personal edition.

Unexpected (too old?) file format

Hi,

What version of Qlik you use?

Can you try by upgrading to latest version.

I've just had this happen to a single QVW file, and in this case the file was corrupted.  Not sure how it happened, but opening the file in a text editor the file appears to only contain blanks, where it should have binary data followed by an XML definition of the file.

It's a case of reverting to a backup, if you have one, or recreate from the project folder - again if you have one.

My best guess of what occurred is an interruption during saving.

It happened to us and created a case with Qliktech and there was no resolution but having a backup of your qvw, anyways there are some recomendations:

Resolution

Unfortunately, I was unsuccessful in opening the QVW. The only solution is to use a backup of the QVW. I apologize but we don't have any methods to recover the QVW. Corruption can be caused by a lot of different issues. It can be caused by other software programs touching the file like antivirus. It can also be caused by network issues. It could be caused by a failed saved QVW.

uninstall-restart!-install solved it for me.

SW Version: 11.20 SR15

as the error repeats, I figured that it happens when I load/save a file from Cloud Server. Try making a copy of your file in your local machine instead, and give it a try as well!
