"the syntax of the equation is incorrect" after upgrading to 2015

I upgraded to 2015 SP4 and my equations are all blown up in my part models.

The error is the same next to all of the "The syntax of this equation is incorrect," but they all worked perfectly in 2014 SP4 right before I upgraded.

When I try to go in and edit none of the cells allow a change. If I delete the value and enter something new it just reverts to the original value. If I delete my global variables to create new ones it won't create any new ones and jest keeps "blanking" the naming column.

Please, any way to fix this would be greatly appreciated. This seems like a huge bug and it is happening on both of the computers that I upgraded. I use these parts to create new ones and they are completely unusable now.

Thank you in advance for your help.

Correct Answer

I encountered similar problems:

Equations broken in SW 2015 SP4

The fix, noted in other messages is:

Suggested fix found in SolidWork KB is

1. Uninstall SOLIDWORKS

2. Rollback update 'KB3072630'

3. Reinstall SOLIDWORKS

Search on that KB number in the forums and you'll see it broke many, many things in Solidworks.

The rollback refers to a Microsoft Windows patch rolled out around 7/14/2015.

Doing the procedure in the order stated above should fix your problem. It is not a good solution, but it does fix Solidworks.

Hey Solidworks! How about a hotfix!

Hello Ramsey,

Indeed I have a collegue with the same output using SW2105 SP4.
It says "syntax of the equation is incorrect".
I tried in my computer and it works fine using the same version and SP. Weird right?
The only difference is I am using Windows 7 and hers is Windows 8

Regards
Jose

  Hi Jose,
  That is weird and I wish I knew how to fix it. I'm using Windows 7 on both computers and they are having the same issue.
  Let me know if you figure it out!
  Thanks

    Upgrading to SW2015 "destroyed" a lot of my old equations created in 2014. I suggest exporting them as a text file, deleting all equations and importing them again.

      Hi Alin,
      I tried that and they all imported with the same errors. Thanks for the suggestion!

    There are a couple of SPRs (565254 and 756132) describing a problem like this when you have your Windows system separator set to comma instead of period. Are you using commas as the decimal separator in your Windows settings?

      Thanks for the input, Jim. I'm not sure how to change that setting, but I'm fairly certain it would be a period instead of a comma. Do you know how to check?
      I re-installed 2014 and the equations are all still intact. It only happens when I open the part in 2015.

  I concur with Terry's solution. I have used it to fix three customer machines today. The symptoms were less obvious in that Toolbox parts were not updating when being configured- but as Toolbox parts heavily rely on equations I found they had errors in the Manage Equations dialogue. Then the simplest of mathematical equations couldn't be resolved either (i.e. =2+2).
  My fix was slightly different though, I invoked the registry solution which related to that same Windows Update (but appreciate tinkering with the registry can be risky) and then only had to repair SOLIDWORKS instead of reinstalling- which may save 30 mins.
  Thanks
  Adam

    Adam,
    I had this problem after I upgraded a few months ago (SW2015, Windows 7) and I don't remember for sure what I did to correct it then except I know I had other issues and unloaded, cleaned the registry, reinstalled and repaired a few times.
    I stopped having this error back then and have not seen a re-occurrence.
    Maybe it was because I cleaned the registry along with my repairs - who knows at this point!
    I did check my Windows update listing and my system does have the Microsoft 'KB3072630' security update installed, but that was just a couple weeks ago, so I don't think that is what actually fixed it for me - I thinks my problem was a month or two ago (so many changes I can't keep track of them all).
    
    Can you explain what the "registry solution" was that you did so I know what to do if this pops up again in the future.

  That did it! Thanks for the tip.
  I had to go into windows update after uninstalling the update to make sure it wouldn't download and install it again.
  So far so good!

I'm having the same problem in 2014 SP4. The funny thing is that the same update is on my machine where the equations work and 3 other machines where the equations do not work.

Hello, my name is Maicol Peterson. I am from Brazil (Joinville/SC). I work with SolidWorks API and while I was programming in SolidWorks 2015. When you update an older version of SolidWorks this action reset the "USE SYSTEM SEPARATOR FOR DIMENSIONS". Try change it in "Tools --> Options" menu, maybe can fix.

Hey Guys,

I am experiencing all the same issues as you, except I am running 2016, so the problem hasn't been fixed yet. I am not even trying to do a mathematical equation in some of mine. I am simply linking to a dimension value in my main assembly and it can't even do that. It says something in my sketch has been deleted.

This is what I am getting below, also it added IIF to everything, in 2014 I never used IIF only IF. This software keeps getting worse, I sure miss the good old days of 2012 when everything worked well. This is beyond frustrating, who is testing stuff over at SolidWorks ? (3 blind mice perhaps?)

You give us all these new fancy features but you can't even get your basic functionalities working properly. STOP WORKING ON 2017 & 2018 and focus on 2015 & 2016.

Unfortunately the suggested workaround isn't possible with my setup. I have a lab of computers in a high school and Windows updates are controlled by the district. Does anyone know if Solidworks has released a patch of some sort to fix this? I have students that are working on taking the CSWA exam and using global variables makes much more manageable.

I believe I might have the correct answer to this issue... as provided by my VAR (Hawkridge Systems)...
"This error is usually the result of a corrupted prerequisite. We have a guide on fixing this issue here:
https://support.hawkridgesys.com/hc/en-us/articles/208308748--The-syntax-of-this-equation-is-incorrect- "

The solution involves running/re-installing some VBA modules. Fixed the problem right up. Piece of cake.

  Here's the solution:
  
  If you see the error message for "The syntax of this equation is incorrect" while editing your equations and the equation is a valid one, the VBA prerequisite software may need to be reinstalled. The VBA prerequisites can be found in <SolidWorks installation files>\prereqs. This software is also attached below.
  To repair the VBA prerequisite please run the following:
  vba71.msi
  vba71-kb2783832-x64.msp
  vba71_1033.msi (For English versions)
  If you are not using the English version, you can run the appropriate file by hovering over the different files and selecting the correct version.
