Extra info :
I tried installing the vCenter converter on a different machine without avail.
I'm not using USB / Flash storage.
Do you need any more information?
Same issue here, anyone got a fix ?
Fix (yet a rather crude one) was restarting the vcenter server. If notifications are queued, Restart VMware vCenter Update Manager Service.
Had the same issue.
All I did to resolve the issue was Stop and Start the following services on vCenter:
VMware vCenter Converter Integrated Server
VMware vCenter Converter Integrated Worker
Then I restarted the vSphere Client and all is fine.
vCenter Server v4.1.0 Build 258902
vCenter Converter 4.2.0
Thank you Alex!
I had the same issue and restarting the Converter services did the trick.
alex's solution worked for me!
I did as instructed and access is working again.
