I don't own a 3Dconnexion mouse but Sharkcad v12 Build 1582 is caught in an endless loop trying to load the siappdll.DDL which doesn't exist on my system.

Using Process Monitor v3.82 the problem is easily observed and including SharkCADPRO
https://docs.microsoft.c...ernals/downloads/procmon

The only mention of 3Dconnexion in the docs
http://docs.imsidesign.c...ommands/File/References/

Anybody know of a solution without having to purchase $100 mouse?

Have you tried downloading 3dxware from the 3dconnexion site?

Yeah, I installed the 3dxware-10 dirver package (672MB), found and copied the dll's used by Sharkcad (siappdll.dll, spwini.dll), uninstalled 3dxware-10, and copied dll's back to system32.

When Sharkcad was idling with no 3dx dll's loaded it was using ~4-6% CPU, with the two 3dx dll's loaded CPU idling has dropped to less than 2%.


Now it spins on registry (40 times a second) looking for
RegQueryValue HKLM\SYSTEM\Setup\SystemSetupInProgress SUCCESS Type: REG_DWORD, Length: 4, Data: 0

and
RegQueryValue HKLM\SYSTEM\Setup\PnpSetupInProgress NAME NOT FOUND Length: 16

and various keys and values under
HKLM\System\CurrentControlSet\Control\DeviceClasses\{4d1e55b2-f16f-11cf-88cb-001111000030}



This all happens with the main Sharkcad loop
C:\ProgramData\punchcad.log
...
main loop started!!


I tried Viacad Pro v11, same issue.

why uninstalling before checking if SharkCAD launches with the 3Dxware software installed...?

I ran Sharkcad with the full 3dx installation (672MB), Sharkcad loaded two 3dx dll's and then 40 times a second repeated the same bunch of registry queries. After repeating the test a few times I saved the two dll's, uninstalled 3dx and copied the two dll's back to system32 and got exactly the same results.


Since running with the two 3dx dll's loaded I haven't experienced any Sharkcad random crashes! Sharkcad expending a lot less CPU cycles querying the registry than looking for non existent dll's on the file system.
