No fuction definition VLR-REACTORS

[dkerns]

For some reason my AutoCAD randomly just stops running lisp routines with  VLR-REACTORS

The only way I can fix it is by doing a software reinstall from the Windows control Panel

Once reinstalled they work again for a day a week or so then it happens again.

Any Idea what is breaking it?

[kpblc2000]

perhaps trouble based on your lisp reactors. Try (before loading vlr-functions) remove all reactors.

What happens after you use?

Do you still have the problems?

If so, it is probably related to either a damaged install or profile where someone has deleted important support paths.

I have had recently a plague of profile corruption.  The fix is to run the Reset to Default and then rebuild the Profile.  What is causing it is a mystery.  It has happened on both Win10 and Win7.

I'm also having the same problem. How do I turn off the reactors?

I also don't understand why after re-installing AutoCAD, it all works fine for about a week. Nothing noticeable has changed on my end and when I restart my computer and AutoCAD after a few days of normal usage, the error shows up.
