For those - like me - who experience problems with the latest Windows Updates and Aero Glass,the procedure for manually installing symbols is easy. You probably don't even need to install Windows Debugging Tools Just create a txt in C:\AeroGlass or wherever you have AeroGlass installedPaste the following:MKDIR %userprofile%\appdata\local\temp\dllsCD C:\Windows\System32XCOPY "dwm.exe" %userprofile%\appdata\local\temp\dllsXCOPY "dwmcore.dll" %userprofile%\appdata\local\temp\dllsXCOPY "uDWM.dll" %userprofile%\appdata\local\temp\dllsCD C:\Program Files (x86)\Windows Kits\8.1\Debuggers\x64SYMCHK /r %userprofile%\appdata\local\temp\dlls /s SRV*C:\AeroGlass\symbols\*http://msdl.microsoft.com/download/symbolsRD /S /Q "%userprofile%\appdata\local\temp\dlls"Save the file and rename it to symbols.cmdRight Click and run as AdministratorThat's it, the Symbols folder should have been created inside your aeroglass installation folder! Hope this helps PS maybe info like this should be part of the OP, or be included in a readme or somewhere on aeroglass site? *hint hint*
