Assembly opening error - 'Ignoring attempt to deallocate unallocated memory'

george.mcintyreQV7G4 — Thu, 25 Aug 2022 07:23:36 GMT

I have an assembly, not very complex, that I am unable to open. I can see the file (.iam and its .idw) in the location they have always been in. I am able to open all sub assemblies, just not the top level one. When I try to open the assembly I get an error message " Ignoring attempt to deallocate unallocated memory" and nothing happens. I have searched for solutions online but cant seem to find anything. Has anyone had this problem before or know how to fix it?

From a google search, I am seeing this:
"Memory allocation and deallocation are managed by the operating system’s virtual memory manager, which uses a Paging technique."
So, if that's the case, make sure that you didn't disable your paging file and that it is toggled-on for "System Managed".

Hi! This type of error usually indicates some sort of corruption (file or memory). Please try the followings.

1) Close Inventor. Go to File Explorer -> %temp% -> clean up as many files as possible.

2) Make sure all critical Windows updates are installed and the graphics driver is updated.

3) Install the applicable Inventor updates.

Many thanks!
