Inventor 2018.3 - Failed to launch server application

[karthur1]

From time-to-time, I get this error while working in Inventor. 

After this error, I then see this error.

The second one is understandable, since Excel did not start. I only see this sometimes when I am editing my structural parts.  Parts like I-Beams, Angles, channels....etc. I have an embedded excel sheet in them so that I can easily change the member section size when needed.  In the part, there is also an ilogic code that triggers excel to run if there is a change to certain parameters in the part.

trigger = Height+Width+Thickness
iProperties.Value("Project", "Description") = GoExcel.CellValue("3rd Party:Embedding 1", "Sheet1", "B2")
iProperties.Value("Summary", "Title") = GoExcel.CellValue("3rd Party:Embedding 1", "Sheet1", "B2")

What I can't figure out is what keeps the excel application from launching when called to do so.  It doesn't happen all the time or on a particular part. If this error occurs when I am actually changing the member size, then that is a problem, because the callout for the member size will be wrong in my parts list, the wrong member size gets purchased, built... or even shipped wrong.  It all heads south at that point.

I tend to think that this is because of MS Office 365 simply because I used Inv 2018 along with Excel 2007 and did not ever have this error. Since upgrading (if you want to call it that) from Excel 2007 to MS Office 365 I now have this new unwelcome feature.

Any ideas on what to do to fix this issue?

Hi Kirk,

Do you get the "Failed to launch server application" message when you try to edit the embedded sheet?

[karthur1]

It is usually when I am editing the part, but not specifically editing the sheet itself.

Does it happen often?
You could try disabling iLogic to see if it happens when no rules are running. I'd recommend doing that in a temporary copy of the part, to avoid saving files that are not up to date.
Can you post one of the parts, or a simplified part that shows the same problem?

[karthur1]

Doesn't happen that often. I'll try to watch it and post a part when I see it happen the next time. Thing is it wont happen every time with the same part.  That is, I can't really reproduce it.

If the problem was only with iLogic, I would have an idea about how to fix it. But it doesn't sound like it's only with iLogic.
You have completely uninstalled the older version of Office?

The best I can tell, only MS Office 365 is installed.

I also get this error, I have a .Net add-in that is reading info from embedded excel sheet. occasionally i get this error.

Any idea what causes this? In my case it reads the data anyway.

Hi! Please make sure .Net 4.6 is installed on your machine, since Inventor 2018 needs it installed to run properly. Also, you may want to start a commandline window (CMD) and go to Inventor 2018 install folder \Bin\. Type in "Inventor.exe/Install" to register it with Windows.

Many thanks!
