Solution:

RevitWorker.exe Running as Administrator

If the RevitWorker process is run as an administrator while the Revit process is not, then Revit will not be able to properly communicate with the RevitWorker. Test if this is happening, by going through the following steps:

Right click on the Revit icon (from the Desktop or Windows Start menu)

Select Run as Administrator.

If you don't have administrative rights available to run Revit as an administrator, work with your computer/operating system support to do this test.

If the error is cleared, then this indicates RevitWorker is running as admin.

Fix RevitWorker

If you've confirmed that RevitWorker is running as admin, go through the follwoing steps to change this:

Go to the Revit installation directory (by default it would be C:\Program Files\Autodesk\Revit ####).

Right click the RevitWorker.exe file and select “Properties”.

Select the “Compatibility” tab.

Clear both the “Compatibility mode” and “Run this program as an administrator”.

Select apply and then OK.

Start Revit normally (without using “Run as Administrator”).

Windows issues

Problems with the Windows setup/configuration can lead to this behavior. Check with your computer/operating system support on the following topics:

System Information "Can't Collect Information":

Go through the following steps to check if this issue is occurring:

Click the Windows Start button.

Type msinfo32.exe.

Click on System Information (App).

Check if System Information shows "Can't Collect Information" as shown in the following picture.

If this is confirmed, it indicates that the Windows Management Instrumentation service is not working properly.

Run Batch to fix

If the error above is found, run the following batch script to restore the Windows Management Instrumentation functionality.

Create the file WBEM_Fix.txt in the folder C:\Autodesk (location can be changed but avoid the Desktop or user folders).

Add the following text to WBEM_Fix.txt: 

@echo on

cd /d c:\temp

if not exist %windir%\system32\wbem goto TryInstall

cd /d %windir%\system32\wbem

net stop winmgmt

winmgmt /kill

if exist Rep_bak rd Rep_bak /s /q

rename Repository Rep_bak

for %%i in (*.dll) do RegSvr32 -s %%i

for %%i in (*.exe) do call :FixSrv %%i

for %%i in (*.mof,*.mfl) do Mofcomp %%i

net start winmgmt

goto End

:FixSrv

if /I (%1) == (wbemcntl.exe) goto SkipSrv

if /I (%1) == (wbemtest.exe) goto SkipSrv

if /I (%1) == (mofcomp.exe) goto SkipSrv

%1 /Regserver

:SkipSrv

goto End

:TryInstall

if not exist wmicore.exe goto End

wmicore /s

net start winmgmt

:End

Rename the file extension from *.txt to a *.bat.

Right click on the BAT file and select Run as administrator.

A Command prompt will appear and will perform several steps. Let the process run until it closes automatically.

Start the Revit again.

If the RevitWorker error continues and System Information App still shows "Can't Collect Information".

Work with your computer/operating system support to resolve this behavior.
