RAC won't Launch

[Mike_Maloney]

One of our sister offices got RAC 2009 installed a couple of days ago, and now they're running into problems with launching. Seems they we're okay the first day, but now when they click the icon, it "blurps" quickly, and then nothing. I read on the ADESK site last night on the Support site, dtd 10 Apr 08 the there was an issue with one of the dll fines for 2008, but didn't find anything for 09. Anyone else run into this yet?

Like my previous post, I'm getting my seats today, so I haven't experienced it, nor have I had any problems on my M90.

Thanks,

I'm not sure if it still happens on Revit 2009, but this is the solution for the same problem on Revit 2008: (from Revit Support Team)

We have seen a number of cases where a Revit product fails to run after the computer is rebooted after Revit is installed. Often the software will run once and then not run when users log out or reboot the computer. We are currently investigating this issue with the help of our development team and there are a number of possible workarounds to the problem that may allow Revit to run on their machines.

They may be able to Right click on the desktop shortcut for Revit and select "Run As…". Then, click OK. If Revit does not run they may need to select the option for "The following user:" and log in as an Administrator. In many cases this has allowed Revit to start, however, in some cases, mapped network drives on the machine may not be recognized from within Revit.

There are two windows system registry keys that if renamed may allow Revit to run correctly. It is possible to rename these two keys, reboot the machine, and Revit will start successfully from then on, however, we recommend caution when attempting to do this. These two keys are not registry keys for Revit, but for the operating system, and deleting or renaming these two keys could result in a Data Execution error from Windows Explorer and cause serious system problems. Make sure to backup any important data before editing the registry. You may not see these keys in the registry - if this is the case, then they are not the problem.
Here are the keys to look for on the client's machine:

To access the registry editor, go to the Start menu and click Run on Windows XP. In the run dialog, type REGEDIT. Then find the following two registry keys and rename them by adding – BACKUP to the end:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers\
REG_SZ: $WinDir\Explorer.exe

HKLM\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\NoExecuteState\
REG_DWORD: LastNoExecuteRadioButtonState

Warning! Problems caused by improperly editing the Windows registry could render your computer operating system unusable. Microsoft provides a wealth of critical information that you need to know about the registry in the Microsoft Knowledge Base at http://support.microsoft.com/support (http://support.microsoft.com/support).

Let me know if these suggestions help. We understand the critical nature of this problem and the impact that it is having on our customers. We are working with our development team to solve this issue and are sorry for any inconvenience it may cause. We will keep you informed on any updates on this issue as they are available.

If you have any questions or would like to add anything additional to this support request please feel free to reply to this email and we will be glad to help.

Best Regards,

Autodesk Support Team

I hope it helps

Thanks Andre,

FYI, I think the other office already tried this, and no go.

Will keep working and will let you know

Thanks

Did some more looking and finally found another fix. It's the RWUXThemeSU80.dll file. There's one for RAC 2009 at this link.

http://usa.autodesk.com/adsk/servlet/ps/item?siteID=123112&id=11245327&linkID=9243099

We had the problem on 5 machines and this seemed to clear it right up. We also did the fix...



HKLM\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\NoExecuteState\
REG_DWORD: LastNoExecuteRadioButtonState


in conjunction with the RWUXThemeSU80.dll file and all seems to be working smoothly now.

Hope this helps... Good Luck!
