CLR20r3 error

[vjc]

Recently, on one of the computers where OD was installed, OD now fails to start. The error that I have been getting is

Description:
Stopped working

Does anyone has any idea what could be wrong. I have tried reinstalling from scratch, reinstalling trial version, reinstalled .net3.5 and .net4 as well but nothing seems to be working.

Are you compiling it yourself? The trial version is 7.9.20, which doesn't match the version you reported. It just suddenly stopped working? Or did it stop working when you tried to move to a newer version? I suspect a missing dll. Maybe try a clean install of OD. Uninstall, then make sure that Program Files and Program Files (x86) do not have any OD remnants in them. Then, install the trial version (just the program, not all the db stuff).

Thanks for your quick reply Jordan. Here are the answers to your questions

1. It is not a compiled version but a downloaded version from OD.
2. The problem occured all of a sudden. We were not updating or anything.
3. I had a older trial version saved with me and I was trying with that.
4. Did a complete uninstall (made sure that the open dental folders were deleted) and reinstalled but the same CLR20r3 error.

Then I unistalled the MySql alongwith database (since it is a backup PC) and tried to reinstall everything from scratch using the older trial version (run as an administrator). Succeded in installing OD and MySql but installation failed when it came to creating my.ini file and I got the following error.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Since all this is happening on my Home computer which is used for backup purposes, I am not panicking but I want to ensure that I have it running so that I can keep backups on it.

You ran as admin and you still got that error? Since the error says UnauthorizedAccess, it certainly seems to be a Windows user permission issue.

As for the original error, I'm just not sure. I'm not in front of our knowledge base right now, so I can't look up that error. Have you considered your antivirus software as a possible culprit? It could also be a video card, a missing Windows update, or a virus on your computer. I'm not sure. What version of Windows?

Hi Jordan
The my.ini installation issue has been solved. I installed the new trial version and it installed everything fine.
However the original problem is still persisting. I also feel that it has to do something with windows and not with OD at all as the other PC's are running it fine. Will try to figure it out, otherwise will format the HDD and reinstall windows from scratch and go from there. (time consuming)
The new error code that I got with trial version is

Thanks again

Hi Jordan
Finally I managed to get rid of the problem. It seems that somehow the Arial font was missing (I still dont know how) and the webpages were also looking a different in the browser. I reinstalled all the fonts of Arial family and everything was as smooth as ever. OD now runs like a charm.
Thanks for your efforts

[jordansparks]

Arial font is one of the things listed on our troubleshooting page, but I didn't suggest that because I thought the failure presented a little differently. I'm glad you got it settled. It's odd that the font suddenly went missing.

[fyc2001]

had the same CLR20r3 error on my XP SP2 machine after running CC Cleaner. the issue seems to be the font, as prev post suggested, I just want to add how to download and install arial font for future ref.
go to
http://www.microsoft.com/en-us/download ... x?id=16083
download
European Union Expansion Font Update

then OD should work.
