Here is the plugin information from there. I'm not sure what is happening. I did a clean install and then used the sketchucation store to reinstall your plugins.

I was thinking that, but I'm having issues even with small files, and other fredo plugins. I Created a new 400kb file and attempted to use Fredo Spline, and it crashes almost immediately every time I try to use it.

• I just open the file, open thrupaint, select the brass material on the faucet or the material on the towel and attempt to paint the towel. That was causing me the most crashes. Also messing with the scale rotate feature after painting.

-I had issues with other large sketchup files crashing too, I don't think it was just this file.

I was able to test it with someone that has sketchup 2025 and thrupaint was working fine no crashes. I think it has something to do with 2020 version.
I was also noticing I can't always get the Thrupaint dialog window to load, I have to click around several times sometimes it will open sometimes it won't.

Thank you!

Ok I did a full uninstall, restart, right clicked run as admin, installed. Everything is still crashing. Here is a video while using Thrupaint.

Hi Dave, I am very familiar with how to install programs as an administrator. No where did I say I'm running sketchup as an administrator.
I did a repair install as an administrator. I will say this again, this problem started before I changed or did any repair installs. It happened before and after.

This definitely has to do with Thrupaint or other fredo plugins to some degree. I did some tests where I tried to use it and it crashes sketchup every time within 1 to 2 mins. Whatever the recent updates were to the plugin changed something.

This is what it keeps doing to my tool bars. I was just using Thrupaint and it crashed. This is how my file opens after

It was already set to run as administrator, I had to give permission to repair. I was getting these errors and issues before doing that too.

No I was getting these errors and sketchup crashing just this week prior to doing anything. I haven't changed anything with my installs. When I opened sketchup this week it asked me to update fredo6 which I did. I was also having issues with thru paint showing up. So I uninstalled that and reinstalled. It then said my trial expired, so I purchased that. Still was getting these errors and sketchup crashing. Every so often it will crash and then when I reload sketchup all of your fredo toolbars are stacked in the middle of my screen not where I had them. I've had to put them back probably 16 times now. In an attempt to fix things, I did a "repair" install on sketchup, but that did not change anything.

Should I attempt a full uninstall reinstall? anything else I could try before that?

Thank you

Hello, I'm running sketchup 2020 and all of your plugins have recently started causing sketchup to crash all the time. I keep getting these errors. I have attempted reinstalling etc but no luck. any thoughts?
