Help with 643 error

I’m getting “shipworks was unable to prepare your computer, reason code: 643” during installation when running Configure From Scratch. Supposedly related to .net problem. Was told by support to reinstall .net.

I have a Mac running Windows 10 under Parallels. No other problems though I only set it up a couple weeks ago. But no problems with shipstation or stamps.com.

Support sent me a link with instructions for fixing .net, which basically comes down to uninstalling and reinstalling. But you can’t actually uninstall .net, at least on Windows 10. All you can do is turn it off under Programs & Features, which I did, restarted, turned it back on (3.5 and 4.8), including the CWS (?) modules, and restarted again. Same error.

Any suggestions?

Hey Bud,

I am so sorry that you haven't been able to get ShipWorks up and running, I am going to see if I can locate your support ticket to see what other recommendations we can try. I will reach out via that ticket/email address to see if we can get you up and running. If I am unable to locate that ticket, I will create a new one using this account. Nevertheless, we will reach out, follow up, and get your ShipWorks up and running.

Thanks,

Gerald

Try disabling the .net version 3.5 and keep 4.8 on then restart. Might want to also check if 3.5 is the default environment variable for PATH if the problem persist, in which case you would want to change it to the later version.

Just some quick thoughts.
