    2018 SP0.1 Web2

    Martin Solem

      Hey forum,


      I have a problem running 2018 SP0.1 Web2 on a new Windows Server 2016 virtual machine. Everything looks good, IIS is fine, i can access <webserver> but when i try to access <webserver>\SOLIDWORKSPDM (default) application pool, my browser just freezes, and on the server-side, the process w3wp.exe is using 97-100% CPU. The same thing happens if i try browsing on the server.

      Installation runs fine, files are in place, local view is in place, the whole thing is set up by the book and i have spent hours troubleshooting what causes this. Local client works fine, all users that i have tested have logged into the local vault view first. Registry looks OK. All rights to folders and the application pools has ben cross-checked countless times, firewall is shut off. I am at a dead end. I have also tried creating a new application pool, and even tried to remove and reinstall Web2 and IIS7.

      As a last resort i have set up a brand new 2016 server, which has only IIS and Web2 files installed, but i'm getting the exact same errors and behavior.

      There is nothing in the PDM Client log, but this from the Event Viewer:


      This appears when i kill the w3wp.exe process:


      A process serving application pool 'SOLIDWORKS PDM Web2' suffered a fatal communication error with the Windows Process Activation Service. The process id was '3660'. The data field contains the error number.

      Event ID: 5011

      -Reported from WAS


      Sometimes an error has been logged, right before i kill the w3wp.exe process, saying something like:

      The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID


      and APPID


      to the user CCS-WEB-02\Administrator SID (S-1-5-21-1124329904-2597292670-2506141146-500) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

      -Reported from DistributedCOM


      I think have managed to fix these by adjusting Launch and Activation permissions in DCOMConfig, they belong to "Runtime broker" and there was another too, with just some Application ID.



      I am now on my 3rd webserver, and they are all acting the same way. Something is dead wrong here, and it could easily be me, but i cannot see what it is.


      Has anyone deployed Web2 successfully on a Win Server 2016, and/or is anyone aware of something the installation manual doesn't cover in Win Server 2016?



      Kind regards,

          I haven't tried but I would suspect it's dependencies. I'd start with making sure ASP.NET is registered:

              Or try the steps outlined in S-071653

                Thank you Charley,


                I have done a couple things different on yet another webserver.

                I used the SOLIDWORKS Installation Manager to install the client and web2 server, to make sure all prereqs are in place.

                Then i ran the command for registering ASP.NET, which completed successfully.


                The same thing happens - absolutely nothing, IE/Chrome is not responding, and w3wp.exe is taking up 97% of CPU.


                As far as S-071653 goes, that is "not an option" in 2016:


                Start installing ASP.NET (4.0.30319.0).

                This option is not supported on this version of the operating system.  Administrators should instead install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Windows Features On/Off" dialog,  the Server Manager management tool, or the dism.exe command line tool.  For more details please see http://go.microsoft.com/fwlink/?LinkID=216771.

                Finished installing ASP.NET (4.0.30319.0).


                And in Server 2016 it's IIS 10 and ASP.NET 4.6, so even that message seems outdated.

                I've had similar problem on Windows Server 2012R2:


                I have into same issue with high CPU usage from w3wp.exe. I manage to solve the issue by checking Event viewer for errors. The cause for Web2 not working was the following:


                Souce: Application Error


                Faulting application name: OILink.exe, version:, time stamp: 0x5711461a

                Faulting package-relative application ID:


                It looks like there was a problem with MSVCP120.dll so I had to reinstall vcredist12( both x86 and x64). I don't know if both are needed but I installed them anyway. VC2013 wasn't listed in PDM prerequisites so I didn't install it but I think they should list it at least for web2. I am not sure if it was corrupt or missing but installing vcredist12 seems to have solved the issue for me.


                Now Web2 app loads successfully.


                Hope this helps.

                    Hi, thank you. Unfortunately, my Eventlog has no recorded errors.:(

                      Miha Ravsel,

                      I didn't try this immediately as i was creating an SR to SOLIDWORKS support at the same time, and wanted to have the error in case they wanted to have a look.


                      They suggested i go through with your solution, and lo and behold, it works! Microsoft Visual C++ 2013 Redist. should DEFINITELY be on the prereq list for Web2.

                      Thank you so much, you have no idea how much time i spent on this!



                      There is now an SPR for this:

                      SPR 1063460 - 'Update the Web2 Prerequisites in the installation guide with C++ 2013 Runtimes in order to use 2018 Web2 - Without them the Login page will hang and 'IIS Worker Process' shows high CPU'



                      SPR is implemented for 2018 SP3 release.
