Woohooo! I installed QV10 on the server where this (large) corrupted QV file exists, and tried the "Layout Rescue" option above. It worked! A data-reduced version opened up, including the full UI and script, which is exactly what I was after. Save'd As, reloaded, and everything is working fine.
Running "Script Rescue" in QV11 also worked, for the script, but we needed the UI dev updates more.
I'm going to [lightly] abuse our developer for not saving backup copies more often while developing, but this solution saved us many hours of re-coding. Thanks!!
The same doubts about this post that maybe you can help me. I changed my computer and I tried to copy my QVW to new computer but when I tried to open I got the mensage about “failed to open XXX.QVW”. If someone open my file in a QVW licensed and save as, will it possible to open in my new computer?
