Relentless exceptions

[Zerozeddy]

Practically everything I do now causes a NullReferenceException error in Flare. Just trying to change the view, selecting open file tabs, dragging a file into a ToC, everything.

In the past I've sent the error report to MadCap every time it happens, but seeing as no matter how much I try to overload them they never get back to me, so I guess it's forum time...

Can anyone advise how to avoid this:

Code: Select all

<MadCapExceptionLog protocol="1" 
                                  executable="Flare"
                                  executableVersion="11.1.2.0"
                                  localDate="2017-02-15T15:52:29.8590541+00:00">
  
    <OS arch="x64"
           frameworkVersion="4.0.30319.42000"
           version="Microsoft Windows NT 6.1.7601 Service Pack 1" /> 
  
    <Exception type="System.NullReferenceException"
                      message="Object reference not set to an instance of an object." 
                      stackTrace="
at B3.CatapultProjectKit.DependencyComputer.CacheTargetLinks(Dictionary`2& mTargetLinks, Dictionary`2& mTargetFiles) 

at B3.CatapultMdiEditorKit.LinkViewerDialog.OnDoBackgroundThreadTask(EventArgs e) 

at B3.AppKit.Dialog.OnDoBackgroundThreadTaskRoot()" source="B3.CatapultProjectKit" /> 

  <User machineID="b5e36f2ba5fc065b3a06002dd5b35544f7c80a42" /> 
  </MadCapExceptionLog>

Or is this really not the right place to ask such a question?

(and does anyone know if Flare developers bother looking at the error reports you send?)

Flare 11.1.2 (32-bit) on Windows 7 SP1 64-bit

I would uninstall Flare and absolutely reinstall .Net as well.

If you have a licence to upgrade to Flare 12 I'd do that or upgrade to Windows 10 (but these don't help with your immediate problem).

Wish I had something better for you but I'd start with .Net (although I'm sure that's been recommended to you already).

Just done the .Net suggestion and seems to have worked. Thank you very much!

Something else you can try if a project is misbehaving is to quit Flare, delete the Analyzer and Output folders and try again. Sometimes the database in the project gets corrupted, so when you delete the Analyzer folder, Flare has to rebuild the database. That often fixes problems. Worth giving it a try.
