"Mesh Files Differ from Host"

You might of got a bad install. Try to reinstall everything and see if that fixes it. And it could of been that host had a mod enabled.

My friend has the retail package for Trinity.  I have the retail original game Sins of a Solar Empire.  I purchased Entrenchment and Diplomacy on Impulse.  He runs XP, I run Vista 32bit.  We also had this error.

I found a solution after 7 hours.

The solution was for him to zip all of his Diplomacy MESH files (3 files) and send them to me.  I deleted all of my MESH files in Diplomacy and put his in.

We did the same thing for Entrenchment.  Now it works.

Now for how I got there.

He purchased his copy more recently, so we believed originally that my copy was out of date.  My copy wouldn't update anymore on Impulse, so I deleted everything from my computer and reinstalled it.  I started with my SoSE disc, and then downloaded and installed Entrenchment and Diplomacy.  Same problem.

I deleted it all again.  First I uninstalled using the control panel.  Then I deleted the C:\Program Files\Stardock Games\Sins of a Solar Empire folder.  Then I deleted the C:\Users\Destroy\AppData\Local\Ironclad Games folder.  Then I opened Impulse and Downloaded the entire client.  That didn't work.

Then He deleted all of his files using the same method as just stated above, and installed everything using his Trinity disc, and then updating with Impulse.  Same problem.

Then he deleted all of the files as above, downloaded the entire client from Impulse, and we tried that.  Same problem.

I logged into his account to make sure that the difference wasn't between Trinity and the original SoSE.  I uninstalled everything as above, and then using HIS account, downloaded the entire Trinity Client.  Same problem.

We found that in this state we could play the original Sins of a Solar Empire, but still couldn't play Entrenchment or Diplomacy on either Ironclad Online, or through direct IP connections.  He zipped his Entrenchment MESH files C:\Program Files\Stardock Games\Sins of a Solar Empire - Trinity\Entrenchment\Mesh and sent them to me.  I deleted all of mine and put his in.  I did the same for Diplomacy, and now we can play.

Here's another thread on the subject. http://forums.sinsofasolarempire.com/381819

It says there is a way to "verify installation" after deleting mesh files. For the life of me I can't find the "verify installation" option in impulse. Maybe it is no longer an option or I'm just missing something.

We had issues with some 3rd party games and the verify option, so we made it harder to use without knowing what you were doing.  If you hold down 'shift' when you right click, it will be there.  Here's the full instructions:

To clear out your mesh files, you'll need to go into the application folder (right click in Impulse, select 'Open application folder'), and there are three different 'Mesh' folders. The first is in the root folder, and there may be two more, depending on which version of the game you have, in the \Entrenchment and \Diplomacy folders. Delete everything in those folders, then shift-right click on the game(s) in Impulse, and select 'Verify Installation'. Impulse will check the integrity of the installed application, and an update should be made available in Impulse. This is not an update to a newer version, but simply Impulse using the update mechanism to replace the missing files. Once you complete the update, reboot your computer.

Do this on all the computers, and you should be good to go.

Ah, thanks for replying. I was wondering what I was missing
