- Check that these files exist:
C:\Windows\System32\UIAutomationCore.dll
If not goto:
"C:\Windows\winsxs\amd64_microsoft-windows-uiautomationcore_31bf3856ad364e35_6.1.7600.16385_none_0c0d85465bcceb37"
From there... Copy/Paste the "UIAutomationCore.dll" to "System32" directory.
Optional, only if ac doesn't start after copying the files.
Then open a cmd and run as admin then type without quotes "cd C:\Windows\System32"
Press enter.
Then type exactly as below:
regsvr32 UIAutomationCore.dll
And do the same for the one below.
C:\Windows\SysWOW64\UIAutomationCore.dll
If not there goto:
"C:\Windows\winsxs\wow64_microsoft-windows-uiautomationcore_31bf3856ad364e35_6.1.7600.16385_none_16622f98902dad32"
From there... Copy/Paste the"UIAutomationCore.dll" to "SysWOW64" directory
Again optional, only if ac doesn't start after copying the files.
Open another cmd and run as admin then type without quotes "cd C:\Windows\SysWOW64"
Press enter.
Then type exactly as below:
regsvr32 UIAutomationCore.dll
- Some users have reported that they cannot start the sim if their main audio device is disabled. Obviously, enabling it solves this issue.
- The windows firewall dialog might be requesting access for acs.exe - accepting the rule exception addition can solve this. If the dialog doesn't show up, you might have to go through the windows control panel options for the firewall and set it to allow acs.exe
* in Windows by default this is done by right clicking on the "folder->send to->compressed (zipped) folder"
