If you are still having an issue with installing VMware Converter, then please provide the following;
1. A screen shot of the full error that is being thrown?
2. The exact version/build of Converter you are trying to install
3. Are you installing as the local administrator account?
4. Is there any other VMware software installed on this machine?
Had a similar issue on a IBM x335 running Windows 2000 server SP4 with rollup SP4 installed.
I installed VMware vCenter Converter Standalone (v 4.0.1) locally on the server which required a reboot. I started the conversion task using the local admin creds of the server and pointed to an ESX 4.1 host, originally I made the mistake of pointing it towards a vCenter server, oops.
Installing the converter on the local server seemed to work for me. Hopefully it will work for you. Good luck.
Could you upload log bundle?
Am I the only one here thinking he probably resolved the issue and doesnt have the logs anymore? since its been more than 7 years?
I've see an update but not check times...
