Rubberduck version information The info below can be copy-paste-completed from the first lines of Rubberduck's log or the About box:

Rubberduck version Any Version
Operating System: Microsoft Windows NT 10.0.18362.0 x64
Host Product: Microsoft Office x64
Host Version: 16.0.12430.20288
Host Executable: MSACCESS.EXE;

Description After I installed the update pre-version (Rubberduck v2.5.0.5381-pre). I got that error. I was able to use MS Access yesterday. When I'm about to work today and saw that there is a new update, I went ahead and install then I got this error. I tried to go back to the last working version that I was able to use (Rubberduck.Setup.2.5.0.5367-pre), still getting the error. I installed the latest green release (Rubberduck.Setup.2.5.0.5244) still getting the error.

To Reproduce Steps to reproduce the behavior:

1. Install pre version (Rubberduck v2.5.0.5381-pre)
2. Launch MS Access.
3. Open visual basic editor.

Expected behavior Everything will load just fine.

This seems to be deep within the entrails of configuration loading. Could you try reinstalling Rubberduck to see whether that fixes the problem? if not, can you attach your user configuration?

Hi,

Yes, I already tried to uninstall and reinstall different pre versions and green versions of RD but I am still getting the error. Where can I find the user configuration?

[djrivers]

Found it. Here it is,

I got it working now so I'm closing this. Thanks.

[bclothier]

Do you mind sharing what you did to get it working? It may be helpful for others in future.

[djrivers]

Of course. I just followed the path C:\Users\Darren\AppData\Local\Microsoft_Corporation\DefaultDomain_Path_xjc5kco13wcyjoec1mjbd3rf33or2jio\16.0.12527.20242\user.config and found that the user.config is corrupted. There were several other folders there that when I opened contains the same file (user.config) that is readable. I just copied it and replaced the file in that directory. I launched MS Access and RD started loading.
