Hi @Anonymous,
I understand your Revit 2011 product crashes when trying to select walls in a project file.
I took a look at the CER report, you´ve sent in, but it doesn´t have enough information to identify what is causing this issue.
If this behavior is specific for a certain project file or a certain wall even, than, please, send me the project file and let me know, how I can find the walls to reproduce the issue.
If this is not specific to a certain model, but reproducible with multiple files on your machine, try the following:
- Repair the Revit installation: Windows Start > Control Panel > Programs > Programs and Features > Uninstall a Program > “Uninstall/Change" > “Repair or Reinstall” > Repair
-
Retest the behavior - if it didn´t help, go to the next step
-
Run a Program Reinstall: Windows Start > Control Panel > Programs > Programs and Features > Uninstall a Program > “Uninstall/Change" > “Repair or Reinstall” > Reinstall
-
Test the behavior in a brand new Windows User Account with Administrator rights
You may also consider upgrading your Revit product to a later release - The latest available build is Revit 2018.2.
Please, mark this post as an accepted solution if it helps, or let me know, if you need further help - I´d be happy to continue assisting you.
Best regards,
